* feat: return 429 when backends are saturated
When backends are at capacity (per-model max_concurrent or the
process-wide --max-concurrent-backend-requests ceiling), the response
was 503. The OpenAI SDK, litellm, and most agent harnesses key on 429
for rate-limit backoff and treat 503 as a hard error.
Both saturation paths now return 429 with the existing Retry-After
header and type: "rate_limit_error" in the JSON body. The per-model
admission middleware keeps admission_rejected as the code field so
existing alerts that match on it still fire.
Non-saturation 503s are unchanged: model cold-loading (with progress
body), model-load failure cooldown, PII detector fail-closed, and
classifier unavailable. These mean "not ready" rather than "busy".

* fix: return 503 when scheduler has no available nodes
When the scheduler cannot find any healthy node to serve a model —
all nodes are full and eviction cannot free a slot, or a node_selector
excludes every candidate — the error fell through to 500. A 500 tells
clients something is broken when the condition is transient and
retryable.
The router now wraps these errors with a new ErrNoAvailableNodes
sentinel. The HTTP error handler maps it to 503 via applyNoAvailableNodes,
following the same pattern as applyBackendAdmission (429). Unrelated
scheduler errors (DB timeouts, registry lookups) still return 500.
Three return sites are wrapped:
- resolveSelectorCandidates: selector matches zero healthy nodes
- scheduleNewModel eviction-busy: all models have in-flight requests
- scheduleNewModel eviction-failed: eviction itself errored
The existing scheduleAndLoad wrapper ("no available nodes: %w") preserves
the sentinel through the chain via errors.Is, as does ModelRouterAdapter.

* fix(quantization): pin the producing backend on imported quantized models (#11875)
ImportModel hands the copied GGUF to importers.ImportLocalPath, which detects
the file format and defaults every GGUF to `backend: llama-cpp`. For a model
this service just produced with a backend stock llama.cpp cannot read, the
generated config names an engine that cannot load the file, and the import
silently registers an unloadable model. Correcting `backend:` by hand makes the
same file work.
The job record already carries the backend that served StartQuantization, so
carry it into the config instead of keeping the detected default. The gallery
publishes a quantizer as a release channel of the engine that runs its output
("llama-cpp-quantization" is llama.cpp's quantizer, whose GGUF is served by
"llama-cpp"), so the channel suffix is stripped to get the serving backend.
A backend that both quantizes and serves ("rocmfp4") carries no suffix and
passes through unchanged, as do pinned hardware variants ("rocm-rocmfp4"),
which are valid values for a config's backend field. An empty job backend
leaves the detected default in place.
Also replace the importer's generic "Fine-tuned model (GGUF)" description for
this path: the model was quantized, not fine-tuned, and the job knows the type.

#12095 added the Animate3D RPC to backend.proto, but the kokoros

A request with narrower allow_patterns hashes to a different CacheKey
than an already-committed broader sibling, so committedResult misses and
materializeLocked re-fetches files the sibling already holds. After the
own-tree reuseMaterializedFile miss, consult committed sibling trees
for the same Source (type+endpoint+repo+revision), re-verify the file
through verifyDownloadedFile (full SHA-256, never size-only), and
hard-link it into the writer's staging snapshot (copy fallback only on
EXDEV). Each file is matched individually against the sibling's
manifest, so a broader request can never inherit a narrower sibling's
gaps as if complete.
The sibling manifest set is loaded and source-matched once per
materialization (files indexed by path) instead of once per staged
file, so a models volume with 20 committed artifacts and a 300-file
snapshot does one manifest pass rather than ~6000 reads and JSON
parses. The sibling-reuse behavior cases live in the package's
registered Ginkgo suite so repository test conventions apply.
