LumpiastyandClaude Opus 5 48f0221c98 server: replace the VRAM doorbell with a want-lock
The doorbell was edge-triggered: a waiter wrote <arena>/doorbell/<pid> and the
holder's warden turned the inotify event into a queue flag. A ring carried no
notion of "still wanted", so it was lost whenever the holder was not already warm
and listening - during its model load (the watch does not exist yet, and the
kernel does not queue events for a watch that is not there) or inside
restore_device - and any ring that survived past the point its sender had been
satisfied caused a spurious release. Lost rings wedged the waiter permanently,
because flock(LOCK_EX) never times out and, with idle-sleep disabled, the holder
had no other reason to release. The wait blocks under mutex_tasks, so the whole
server stopped answering while /health still returned 200.

Express the request as kernel state instead. A waiter holds <arena>/want.lock
shared while it waits and drops it once it owns the token; the sleep decision
probes that lock non-blocking and releases the GPU while anyone is waiting. The
probe needs its own fd - flock treats two open file descriptions of one file
independently, so probing on the waiter's fd would convert our own lock rather
than conflict with it. Nothing can be missed, nothing goes stale, and a waiter
that dies is cleaned up by the kernel.

Probe from should_sleep() on the loop thread rather than from a warden thread.
Routing it through a flag is what made the first attempts fail: start_loop()
holds mutex_tasks from should_sleep() through the callbacks to the wait, so a
warden's request_yield() blocks on that mutex and is admitted only after the flag
has been consumed, latching a release for the next wake. Reading live state where
the decision is made has no edge to latch, and drops the warden's poll latency.

Two sleep-path bugs this exposed: wait_until_no_sleep() waited on !sleeping but
the loop clears req_stop_sleeping on the way in, so a loop that slept again
before the waiter ran stranded it forever - re-ask on every wake. And a task
queued after the waiter saw us awake could not wake us by itself, so sleep now
also breaks on a non-empty queue. Hold the GPU for 100 ms after a wake: the
request that woke us is not queued yet, and yielding at once only sends it round
again.

Measured on the RX 580 pod, two servers contending, 60 alternating handoffs:
0 stranded, median 0.309 s against the doorbell's 0.314 s.

Lumpiasty 04e9aec9bd server: on-demand mmproj - free encoder VRAM on the text path
The vision encoder sits idle in VRAM on every text request. With
LLAMA_MMPROJ_ONDEMAND=1 the server keeps the encoder in RAM (released
after load) and brings it into VRAM just-in-time before mtmd_batch_encode,
releasing it again afterwards - so the encoder's VRAM is free for KV /
expert cache on the common text-only path.

When the encoder does not fit (that VRAM has been claimed), evict the LLM
backbone weights first: they are not needed while the encoder runs (the
decode that uses them happens afterwards), their host shadow is read-only
(cheap free, no D2H), and the KV / prompt cache is left untouched. Order
on the way back matters: free the encoder before re-uploading the weights
so the peak stays within VRAM.

Also wire the encoder release/restore into the VRAM arbiter: vram_go_cold
releases it; the just-in-time encode-path restore replaces the previous
restore in vram_ensure_warm.

Lumpiasty 6564834854 mtmd: release/restore the encoder weights from VRAM on demand
Add clip_release_device/clip_restore_device (and mtmd_release_device/
mtmd_restore_device wrappers over the vision + audio contexts) that free
the multimodal encoder's device weight buffer to a read-only host shadow
and rebuild it on demand, using the same shadow/free/reallocate pattern
as llama_model weights. No-op for a CPU-backed encoder. This lets the
server drop the ~hundreds-of-MiB vision encoder from VRAM when it is not
encoding an image.

Lumpiasty 4597050be9 server: restore weights/KV on wake, not at decode, so KV eviction is safe
With LLAMA_SLEEP_EVICT_KV the KV cache device buffers are freed when a model
goes cold. update_slots() touches the KV before the decode-time vram_ensure_warm
(e.g. SWA models create a checkpoint that reads the KV via ggml_backend_tensor_get),
so the KV must already be resident by then. Move the restore to the sleep-wake
handler (handle_sleeping_state(false)), which runs before update_slots, fixing a
GGML_ASSERT(buffer) crash on iSWA models (gemma) when KV eviction is enabled.

Lumpiasty 35d35d5c31 server: coordinate model load with the VRAM arbiter to avoid load-time OOM
Before uploading a model's weights, acquire the shared VRAM token (ring the
doorbell so any resident model releases first). Previously load uploaded weights
to VRAM before the arbiter was active, so loading a large model while another
(e.g. the warm 4B task model) held VRAM could exceed the budget and OOM.

- add vram_arena_open() (idempotent flock/doorbell setup) and
  vram_acquire_for_load(), called from load_model() before
  common_init_from_params().
- a coordinated load now stays warm holding the token and serves its first
  request without a re-warm (drop the init-time go_cold cold-start).

Lumpiasty ad657136a2 server: keep the sleep-wake path active when the VRAM arbiter is enabled
The request handler only calls wait_until_no_sleep() (which wakes a server out
of its sleeping state) when sleep_idle_seconds >= 0. But the VRAM arbiter's
cross-process doorbell can put a server to sleep even when idle-sleep is
disabled, so without this a doorbell-slept server would never wake and requests
to it would hang until timeout.

Do not bypass the wake path when LLAMA_SLEEP_VRAM_ONLY is set, so the arbiter no
longer depends on --sleep-idle-seconds being configured.

Lumpiasty 811b4fab77 server: optionally evict the KV cache too (Phase 2 of VRAM sharing)
Extend on-demand device residency to the KV cache so that when a model's KV
plus another model would not fit in VRAM, the KV can also be evicted to a host
shadow (D2H on release, H2D on restore) instead of only the weights.

- llama_memory_i: add release_device_buffers()/restore_device_buffers()
  (default no-op). Implemented in llama_kv_cache (D2H shadow of the live
  ctxs_bufs, freed and reallocated like the weights); llama_memory_hybrid and
  llama_kv_cache_iswa delegate to their child caches.
- llama_context::release_device(evict_kv): also evict the memory's device
  buffers when requested; restore_device() rebuilds them. Public API
  llama_context_release_device gains an evict_kv flag.
- server: LLAMA_SLEEP_EVICT_KV=1 enables it. Off by default (weights-only),
  since the KV shadow adds a D2H/H2D copy of the live cache each cycle.

Validated on RX 580 (Vulkan), 4B @ 32k ctx: weights-only cold VRAM 1750 MB
(KV stays); weights+KV cold VRAM 726 MB (KV freed, ~1 GB reclaimed). KV
survives the round-trip: prompt cache reused after the cycle (prompt_n 4 vs
42), correct output.

Lumpiasty 811eb55e12 server: on-demand VRAM sharing to time-share one GPU between models
Add release/restore of a model's GPU weight buffers (keeping a host shadow
and the KV cache) so several always-loaded llama-server processes can
time-share a single GPU without reloading or losing the prompt cache.

- llama-model: release_device_weights()/restore_device_weights() capture a
  compact host shadow (stable iteration order, view-skipping) and free then
  realloc the device weight buffers; weights_resident() query.
- llama-context: release_device()/restore_device() wrappers; decode() auto-
  restores; public C API llama_context_release_device/restore_device.
- server: LLAMA_SLEEP_VRAM_ONLY makes idle-sleep release only the VRAM weights
  (not a full unload/reload). A cross-process flock token in LLAMA_VRAM_ARENA
  enforces "resident iff holds token"; an inotify doorbell forces the holder
  to release on contention. The warden thread only touches the task queue, so
  releases run on the loop thread and never race a decode.

Validated on RX 580 (Vulkan): two models share 8GB, never both resident,
correct output under contention, KV cache preserved (no re-prefill).

Foad Abo Dahood 5d806aa257 server : apply checkpoint min-step eviction only when the checkpoint list is full (#28302)
The spacing eviction in create_checkpoint() keeps the oldest checkpoint and
erases every later one within checkpoint_min_step of it. For prompts shorter
than checkpoint_min_step this drops the checkpoint at n_tokens - 4 that the
next request resumes from, so hybrid/recurrent models re-prefill from the
previous checkpoint instead. Apply the spacing rule only once the list is at
n_ctx_checkpoints, and replace an existing checkpoint at the same n_tokens
instead of appending a duplicate.

Xuan-Son NguyenandPascal 160bd031b2 server: fix LRU hang on multiple requests same model (#28539)
* server: fix LRU hang on multiple requests same model

* server: keep a queued model out of the victim pool until its waiters leave

A waiter that gave up while its model was still loading left the
model idle with no request behind it, and nothing recounted the free
slots, so a second request queued behind it stayed queued forever.
tick() was only driven by requests: join, claim and the end of a
proxied request.

Keep the queue entry alive after a successful claim so the model
coming up is never picked as a victim before its waiters use it, and
recount the slots on every status change and whenever a waiter
abandons the queue. The model is then evicted as soon as it comes up
with nobody left to serve.

Aleksander Grygier 0afb805b19 ui: Improve Chat Messages rendering performance (#28460)
* ui : update active conversation fields in place

updateCurrentNode, applyConversationUpdate, updateConversationTimestamp
and the pin toggle replaced the whole activeConversation object, so its
identity changed on every send, tool result and rename. ChatMessages
tracks that identity to refresh sibling info, so each replacement
triggered a full refetch of every message in the conversation. Write the
changed fields instead, mirroring updateMessageAtIndex.

Assisted-by: pi:zai-org/GLM-5.3

* ui : reuse the conversation load read for sibling info

Opening a conversation read every message from the database twice: once
in loadConversation for the active path, once in ChatMessages for the
sibling map. Hand the freshly read array over once so the chat screen
builds sibling info from it, and set the conversation and its messages
in one sync block so effects never see the new conversation paired with
the previous one's messages.

Assisted-by: pi:zai-org/GLM-5.3

* ui : memoize leaf walks in sibling map build

buildSiblingInfoMap resolves each sibling's leaf by walking the last-child
chain, once per sibling per message, so the walk repeats along the same
chains for every message in the conversation ( O(messages^2) on long
chats ). Memoize leaf resolution per build with path compression so each
edge is walked once.

Assisted-by: pi:zai-org/GLM-5.3

* ui : skip sibling refetch for in-place message edits

refreshAllMessages refetches every message of the conversation just to
rebuild sibling info, but preserve-responses and non-branching assistant
edits never create branches, so the sibling map stays valid. Refresh only
after actions that branch (editWithBranching kept) or delete.

Assisted-by: pi:zai-org/GLM-5.3

* ui : drop unused currentResponse reactive writes

Nothing reads chatStore.currentResponse, but setChatStreaming reassigned
it on every streamed chunk, so each token paid a reactive write and string
assignment for nothing. Remove the field and the clearUIState wrapper
that only reset it.

Assisted-by: pi:zai-org/GLM-5.3

* ui : reuse completed agentic turn sections during streaming

deriveAgenticSections runs in a $derived invalidated per streamed chunk,
but re-derived every turn of the session each time, so per-chunk cost grew
with session length. Cache completed turns keyed by their assistant message
plus reference checks on every field that feeds derivation; only the
streaming turn recomputes. Cache hits return the same section objects, so
tool block props stay stable and skip their per-chunk re-derive.

Assisted-by: pi:zai-org/GLM-5.3

* ui : share markdown block infrastructure

Every markdown block duplicated shared work: a full copy of the hljs
theme CSS per instance, and the remark/rehype plugin chain rebuilt on
every processMarkdown call ( once per block at mount, again per coalesced
chunk while streaming ). Use the single theme style element already
maintained by SyntaxHighlightedCode, and build pipelines once - shared
process-wide for attachment-less blocks, cached by attachments identity
otherwise.

Assisted-by: pi:zai-org/GLM-5.3

* ui : measure assistant layout only for the last message

Every assistant message ran getComputedStyle, getBoundingClientRect and
a ResizeObserver over the previous user bubble at mount, even off-screen
ones, forcing a layout pass per message while a long conversation
renders. The measured vars only feed the :last-child min-height rule, so
gate the effect on isLastAssistantMessage; one measurement and one
observer remain, and the effect re-runs when the last message changes.

Assisted-by: pi:zai-org/GLM-5.3

* ui : trim whole-blob scans in tool block headers

Tool block headers parsed their entire blobs at mount, even collapsed,
and most tool results and args are large plain text or embedded file
content: skip JSON.parse unless the blob starts with a JSON container,
prefilter search-result extraction with a Title:/URL: substring check,
and match the end-anchored exit-code marker against only the tail of exec
outputs.

Assisted-by: pi:zai-org/GLM-5.3

* ui : parse write_file and edit_file titles without the content blob

Both block headers parsed the full args JSON at mount, even collapsed, and
write_file and edit_file args embed the whole file content or edit
strings, so every block paid a full-blob JSON parse just to read the path.
Split the meta into a title tier that extracts the path with a targeted
key match (full parse only as fallback) and a body tier that keeps the
full parse; Svelte deriveds are lazy, and the body snippet renders only
while the block is expanded, so collapsed blocks no longer parse args.

Assisted-by: pi:zai-org/GLM-5.3

* ui : mount chat messages lazily near the viewport

Every message row mounted its full component tree on load, so the cycle
collector, GC and layout invalidation kept walking every live object and
DOM node even for rows the user never scrolls to - which dominated the
profile of long conversations. Wrap each row in a placeholder with an
IntersectionObserver ( two viewport heights of runway ) that swaps in the
real ChatMessage when the row approaches the viewport; the row shell
keeps the content-visibility sizing, and rows stay mounted once
realized. Rows targeted by the pending-edit flow mount eagerly.

Assisted-by: pi:zai-org/GLM-5.3

* ui : smooth the chat navigation animations

Slide the centered new-chat form to the bottom edge with a transform
instead of a bottom offset - layout-property transitions need the main
thread every frame and stutter while a long conversation loads, while
transform transitions run on the compositor. Fade the message list in
with a CSS animation keyed to the conversation id, disabled under
prefers-reduced-motion.

Assisted-by: pi:zai-org/GLM-5.3

* ui : follow the svelte runes guidance in chat message code

Two effects detected changes with manual previous-value refs and reset
flags. The permission request carries object identity, so its dismissal
is now a derived comparing the dismissed request; the continue request
is a bare boolean, so its dismissal only shrinks to a reset while no
request is pending. Also drop a dead if (browser) guard in the markdown
theme loader - effects never run on the server.

Assisted-by: pi:zai-org/GLM-5.3

* test : pin the chat perf invariants in the unit suite

Cover the fixes whose silent regression would be stale or wrong UI rather
than a crash: the turn-section cache must reuse unchanged turns yet
recompute on every field it compares; the sibling map must resolve the
same leaves after the leaf-walk memoization; the active conversation must
keep its identity through field updates; and the blob gates ( exec tail
window, plain-text result gate, search prefilter ) must keep accepting
what they gate. Only the risky invariants are pinned - no coverage for
coverage's sake.

Assisted-by: pi:zai-org/GLM-5.3

* refactor : address review remarks

Name the tool-arg string-field pattern, move the file tools' path field
aliases and the JSON container gates into lib/constants, and export the
write_file / edit_file meta types from $lib/types instead of the parser
modules.

The talker and the code predictor share the hidden size on the 0.6B

to identity when the weight is missing, the loader now agrees.

The code predictor carries a massive activation: its layer 2 FFN
intermediate peaks around 1.5e5, well past the 65504 ceiling of F16.
mul_mat casts its input to the weight type, so an F16 ffn_down turns
that peak into inf, the residual follows, and the next rms_norm yields
NaN. Reference forward in float32 gives 145109 against 145396 measured
in the graph.

Georgi Gerganov bebc9350ec common: rename --tensor-read-lazy to --lazy-mode, add -lzm shorthand (#27969)
Rename the --tensor-read-lazy CLI argument to --lazy-mode, to match the
internal lazy_mode parameter, and add a -lzm shorthand. Sync the READMEs.

Assisted by: pi:GLM-5.3-Flash

* ui: split model option icons into capabilities and modalities

Replace the supportsThinking flag on ModelId with a capabilities object
keyed like ModelModalities, so future capabilities (tool calls, etc.)
slot in alongside reasoning. Icons and labels now come from the shared
CAPABILITY_ICONS/MODALITY_ICONS constants.

Aleksander Grygier fe235f4343 ui: Replace per-conversation MCP overrides with per-conversation tool policy (#27745)
* ui: replace per-conversation MCP overrides with per-conversation tool policy

MCP server enabled state is now global (server.enabled); per-conversation
control moves to disabled tool keys and categories seeded into each new
conversation. Aligns the add sheet with the dropdown options and flattens
MCP tool groups in the tools submenu.

Assisted-by: pi

* ui: keep tool policy migration running when defaults parse fails

A corrupt disabledToolKeys localStorage entry no longer aborts the
migration; it falls through with empty defaults so legacy MCP server
overrides still get converted.

Assisted-by: pi

* ui: fall back to global defaults when agentic flow has no tool policy

Passing empty disabled sets bypassed the global defaults and could
enable tools for callers that do not pass a policy yet.

Assisted-by: pi

* ui: align preferences section headers with their methods

The Reasoning Effort and Working Directory headers sat above tool
policy methods; move them above setCwd and setReasoningEffort. Also
clarify the disabled tools JSDoc: existing rows with an unset field
have an empty policy, defaults apply only when there is no active
conversation.

Assisted-by: pi

* ui: gate MCP server avatars on conversation tool policy

Servers whose tools are disabled for the current conversation (MCP
category or server-scoped key) no longer show as enabled for the chat.

Assisted-by: pi

* ui: drop unused MCP category toggle from tools panel hook

Per-conversation MCP control is server-granular; no component renders
a whole-category toggle, so remove the dead API.

Assisted-by: pi

* ui: skip MCP init when flow policy disables the MCP category

Resolve the effective tool policy before deciding whether to
initialize MCP so flows that will not send any MCP tools skip the
init work. Callers without a policy keep falling back to global
defaults.

Assisted-by: pi

* chore: format

* ui: restore reasoning section in mobile add sheet

The sheet rewrite dropped it; the desktop dropdown still has it.
MCP Prompts and Resources stay out of the sheet on purpose.

Assisted-by: pi

* ui: clear MCP server group key in enableAllToolsForServer

The group key disables every tool of the server regardless of
per-tool keys, so re-enabling a server from Settings did nothing
while it was set.

Assisted-by: pi

* ui: skip MCP init when no policy-enabled server remains

Extends the category-level check: the flow also skips MCP init when
every globally-enabled server has its server-scoped group key
disabled in the tool policy.

Assisted-by: pi

* ui: make Settings tools tab edit defaults with category toggles

Adds per-category checkboxes and a caption stating the tab applies
to new conversations; tool picks inside a chat only affect that
chat.

Assisted-by: pi

* ui: gate cwd picker and mention picker on effective tool policy

Both checked the global disabled set directly, so a conversation
that disabled file_search still showed search as available.

Assisted-by: pi

* ui: clean up tool key helpers and store docs

Documents getEnabledToolsForLLM properly, unstacks the JSDoc at
isEntryEnabled, makes setToolEnabled persist like setCategoryEnabled
(toggleTool now delegates to it), and routes the serverId-less MCP
branch of toolKey through getMcpServerToolsKey so both key formats
come from one place. Preferences banner comments become plain
comments so they no longer read as class member docs.

Assisted-by: pi

* ui: indeterminate group checkboxes and inert grayed rows

A category that is on with nothing enabled under it now shows the
mixed checkbox state instead of a checked box next to 0/N. Rows
grayed out by a disabled parent no longer stay clickable behind
opacity.

Assisted-by: pi

* ui: gate MCP prompt and resource capabilities on tool policy

hasPromptsCapability and hasResourcesCapability accept an optional
set of usable server ids; ChatFormActions resolves it from global
enablement minus the active conversation's policy. Restores the
per-chat gating the old mcpServerOverrides provided; callers without
arguments keep global behavior.

Assisted-by: pi

* ui: remove unmounted MCP submenu component

Never rendered anywhere; its entries are duplicates (prompts and
resources live in the attachment menu, servers in the add menu and
sheet) that would need capability wiring maintained for nothing.

Assisted-by: pi

* ui: fix model information dialog width on all screen sizes

The dialog sets container-type: inline-size, so auto width ignores
its contents and collapses to padding. Give it an explicit viewport
width on mobile and cap at 60rem on desktop.

Assisted-by: pi

* ui: scroll wide chat template in model information dialog

Long unbreakable Jinja tokens blew out the table and dialog width;
the block now scrolls horizontally instead of stretching.

Assisted-by: pi

* ui: use fixed table layout in model information dialog

Auto table layout sizes columns to content min-content, so the chat
template's long lines kept inflating the dialog despite the scroll
wrapper. Fixed layout pins the first column and gives the value
column a definite width the wrapper can scroll within. min-w-0 on
the grid item guards the same path on the grid side.

Assisted-by: pi

* ui: make model information dialog full-screen on mobile

Matches the settings dialog pattern: full viewport below md,
calc-sized and capped at 60rem on desktop.

Assisted-by: pi

* ui: stack chat template row in model information dialog

Label above the block in a single full-width cell, so the template
gets the whole table width and its horizontal scroll is usable on
narrow screens.

Assisted-by: pi

* ui: scroll model information header with the content

The base dialog header is sticky; this dialog overrides it to
relative so the title and description scroll away with the body.
relative keeps the header as the close button's containing block.

Assisted-by: pi

* ui: replace literal comment text in sheet group snippet

A // line inside the Svelte snippet rendered as visible text; use an
HTML comment.

Assisted-by: pi

* ui: let indeterminate state win over checked in group checkboxes

The checkbox indicator snippet renders the check icon whenever
checked, so the mixed state never showed. Pass the checked prop
as false while indeterminate.

Assisted-by: pi

* ui: initialize only policy-enabled MCP servers for a flow

ensureInitialized accepts an optional server id set; the agentic
flow passes the servers its tool policy leaves usable, so servers
disabled for the conversation no longer get connected. Callers
without arguments keep the global behavior.

Assisted-by: pi

* ui: derive group checkbox state in useToolsPanel

Moves the mixed-state derivation out of the submenu and sheet
snippets into one getGroupCheckState accessor; the snippets just
consume checked and indeterminate.

Assisted-by: pi

* ui: gate /prompt command on the conversation tool policy

The slash command's availability now follows the same rule as the
agentic flow instead of the global capability check, so it disables
itself when the conversation's policy leaves no usable MCP server.

Assisted-by: pi

* ui: remove dead MCP prompt menu trigger chain

The /prompt slash command is the surviving trigger; the menu-button
path (onMcpPromptClick, hasMcpPromptsSupport, showMcpPromptButton,
the MCP_PROMPT attachment item and its unrendered item arrays) has
no consumer left. Message display for inserted prompts is untouched.

Assisted-by: pi

* ui: render dash for mixed-state group checkboxes

The accessor refactor dropped the checked-and-not-indeterminate
guard, so the category-on flag won and the dash never showed. The
tooltip keeps using the raw parent flag since clicking a mixed
group still disables it.

Assisted-by: pi

* ui: fix group checkbox sticking checked after disable

Clicking a mixed-state group box let bits-ui optimistically flip
its internal checked flag; the derived checked prop did not change
across the transition (both mixed and off map to checked=false),
so Svelte never applied the settled value and the check icon stuck
while the count already read 0/7.

Pass the parent flag as checked and the mix as indeterminate, so
every group toggle changes checked; render the dash on top of a
checked box for the mixed state.

Assisted-by: pi

* fix: UI for Model Information dialog

* ui: keep MCP connections stable across policy switches

ensureInitialized folds the policy into its config signature, so
alternating two conversations with different policies tore down and
reconnected every server with health checks included. Tool collection
already filters by the flow policy, so initialize every
settings-enabled server instead and never pass a policy into the MCP
config. The duplicated policy-server check becomes one accessor on
ConversationPreferences.

Assisted-by: pi

* ui: remove dead MCP resources menu trigger chain

Same shape as the earlier prompt trigger cleanup: nothing renders the
MCP resources menu button, and the only live entry into resource
browsing is Settings > MCP Servers plus the attachment resource
picker. Drop onMcpResourcesClick, hasMcpResourcesSupport,
MCP_RESOURCES_CLICK, the AttachmentItemVisibleWhen enum and
hasResourcesCapability; the resources display, browser and picker
components are untouched.

Kyozzz 1729ed5371 server : reject prefilled assistant messages with tool calls (#27626)
* server: fix tool calls getting silently stripped with --prefill-assistant

Last assistant carries tool_calls + --prefill-assistant is on → request
flips into continuation mode, add_generation_prompt forced off, tail
rebuilt from reasoning_content + content only. Tool calls just vanish.

- Auto-continuation now skips trailing assistant msgs that have tool calls
- continue_final_message on those throws a clear error instead of
  silently corrupting the prompt
- Regression tests included, red before / green after

Fixes #27588

Developed with AI assistance, disclosed per the contribution policy.

* server : address review: fail on prefill-assistant + trailing tool_calls

Move validation into oaicompat_chat_params_parse (next to the existing
two-or-more-assistant check) and remove it from common_chat_templates_apply,
which has no precedent for validation. Drop the regression tests.

Per review: --prefill-assistant with a trailing assistant message
containing tool calls is not supported and should fail loudly.
