Josh Siviour f9c84919ef feat: co-served GPU model bundles (vLLM + TEI) with family-aware reaper (#845)
* feat: co-served GPU model bundles (catalog, lifecycle, embed/rerank routing)

Serve the generative LLM, embedder and reranker as one co-resident GPU
bundle: EMBEDDING/RERANK catalog modalities + co-serve group, bundle-aware
admission (one GPU claim sized to summed member VRAM), single-flight one-VM
launch with a member->port EndpointRecord, DynamicEndpointResolver member
routing. Ochrevector embed/rerank/token-introspection resolve through the
resolver (static single-endpoint map retired); rerank degrades to plain KNN on
absent/failure. Public InvokeModel-embeddings and top-level Rerank deferred.

* feat: co-serve vLLM+TEI bundle image with per-engine readiness

Replace the single-model vllm-serve unit with a generic bedrock-serve@
systemd template driven by per-member BEDROCK_* env files, dispatching to
vLLM or text-embeddings-router by engine and binding each member to its own
port and weights device. TEI serves directly on its serve port; readiness
probes each member on the route its engine answers (vLLM /v1/models, TEI
/health) with the engine family carried end-to-end from the catalog.

* fix: serve nomic embedder correctly in the co-serve bundle

Bound embeddings requests to the TEI client batch limit so a large
document's chunks are split across requests instead of 422ing. Serve
nomic with explicit mean pooling, since the flat weights layout omits
1_Pooling/config.json and TEI would otherwise default to CLS. Add
bge-base-en-v1.5 as a standalone alternative embedder.

* fix: make the bedrock reaper family-aware and pin-safe

A pinned endpoint is now exempt from terminate-and-relaunch on scrape
failure, mirroring how it is already exempt from idle reclaim, so a
transient unreachability can no longer tear down operator- or
commitment-managed serving.

A bundle with no generative vLLM member exposes no vLLM load metrics, so
it is liveness-probed on /health and kept warm rather than scraped for
idleness on a route it does not serve and reaped in a loop.

* test: lock in co-serve group-member convergence to one VM

* fix: pin self-host HF repo/revision in catalog and stop nested config flattening

Carry HFRepo/HFRevision per self-host catalog entry; weights pull defaults
--hf-repo and --revision from them so a bare pull cannot silently grab a
regressed upstream main (the nomic v5 config.json duplicate-field break).
Restrict fixed config filenames to the repo root so a nested config.json
(sentence-transformers 1_Pooling/) is dropped instead of flattening onto the
model config, and refuse any two source paths that collide at one dest key.

* fix: let endpoint delete clear an account-scoped pinned record and report honestly

A bare 'endpoint delete' resolved the Global key, which never held a pinned,
account-scoped record, then printed 'torn down' over the idempotent no-op while
the record survived. Add --account to the delete command so an operator can
target the account 'endpoint list' shows, and return DeleteEndpointOutput.Removed
so the CLI names a real teardown versus a lookup that found nothing and points
at --account. A gone VM already tolerates NotFound, so a scoped delete clears a
record whose instance was terminated out of band.
