bfab1ded08 v0.28.11 feat: embedding_multimodal_model — separate model routing for multimodal embeddings (#719)
* feat: embedding_multimodal_model — separate model routing for multimodal embeddings

v0.28.9 shipped multimodal image embeddings via Voyage, but
embedMultimodal() hardcodes to the primary embedding_model. Brains
using OpenAI text-embedding-3-large (1536-dim) for text cannot use
Voyage voyage-multimodal-3 (1024-dim) for images without switching
their entire embedding pipeline.

This adds embedding_multimodal_model as a distinct config key that
embedMultimodal() prefers over embedding_model when set. The dual-
column schema (embedding vs embedding_image) already supports
different dimensions — this patch completes the routing.

Config surface:
  - gbrain config set embedding_multimodal_model voyage:voyage-multimodal-3
  - env: GBRAIN_EMBEDDING_MULTIMODAL_MODEL=voyage:voyage-multimodal-3

Files changed:
  - core/ai/types.ts: AIGatewayConfig gains embedding_multimodal_model
  - core/ai/gateway.ts: configureGateway stores it; embedMultimodal reads it
  - core/config.ts: GBrainConfig type + env loader + DB merge path
  - cli.ts: threads config into gateway; reconfigures after DB merge

Tested on a 96K-page brain with OpenAI text + Voyage multimodal
running side by side. Voyage returns 1024-dim vectors into
embedding_image column; text embeddings unchanged.

* refactor(cli): extract buildGatewayConfig + always re-config after DB merge

Two related changes co-located so the un-gate doesn't leave the duplicated
configureGateway shapes drifting:

1. Extract file-local `buildGatewayConfig(c: GBrainConfig): AIGatewayConfig`
   helper. Both configureGateway sites in connectEngine() now pass through
   it; future fields touch one place.

2. Drop the field-name-gated re-config trigger. The previous gate fired
   only when `merged.embedding_multimodal_model` was truthy, coupling the
   trigger to one field name. Future DB-mutable gateway fields would
   silently miss it. Re-config now always fires when loadConfigWithEngine
   returns non-null. One extra cache+shrinkState clear per startup is
   microseconds, no hot path.

Schema-sizing fields stay stable because loadConfigWithEngine respects
file/env first; merged.embedding_dimensions equals config.embedding_dimensions
when no DB override exists.

* feat(ai): model-level multimodal validation + getMultimodalModel accessor

Codex review of PR #719 (F1) caught a real footgun: the Voyage recipe
shares supports_multimodal: true across all 12 models in its embedding
touchpoint, of which only voyage-multimodal-3 is valid at
/multimodalembeddings. A user setting embedding_multimodal_model to a
text-only Voyage model (e.g. voyage-3-large) passes local validation and
fails at the endpoint with HTTP 400 — which gateway.ts:626 misclassifies
as transient (TODO: reclassify, tracked in TODOS.md).

Adds:
- EmbeddingTouchpoint.multimodal_models?: string[] (optional, model-level
  allow-list inside a recipe that mixes text-only + multimodal models).
- Voyage declares multimodal_models: ['voyage-multimodal-3'].
- embedMultimodal() validates parsed.modelId against the allow-list AFTER
  the existing recipe-level supports_multimodal check. Throws AIConfigError
  with the full multimodal_models list in the fix hint.
- getMultimodalModel() public accessor mirroring getEmbeddingModel /
  getChatModel — needed by the cli-multimodal-integration test and useful
  for future doctor checks.

Recipe-level fast-fail stays so non-multimodal providers (Anthropic /
OpenAI today) keep their AIConfigError path unchanged.

* test: cover embedding_multimodal_model precedence + gateway override + cli integration

PR #719 originally shipped zero tests for the new code paths. Closes
that gap with three layers:

1. test/loadConfig-merge.test.ts — extends the existing env > file > DB
   precedence pattern (which already covers embedding_image_ocr_model)
   with four cases for embedding_multimodal_model: DB-only fills in,
   file wins over DB, all-unset stays undefined, null/empty DB ignored.

2. test/voyage-multimodal.test.ts — four cases for embedMultimodal model
   resolution: prefers multimodal_model over embedding_model, falls back
   to embedding_model when unset (regression guard), AIConfigError on
   non-multimodal recipe, AIConfigError on Voyage text-only model
   (Codex F1 model-level validation).

3. test/cli-multimodal-integration.test.ts (NEW) — three PGLite-based
   integration tests for the cli.ts re-config glue itself (Codex F3:
   the actual bug site that "mechanical glue" claims hide). Drives the
   loadConfigWithEngine + buildGatewayConfig + configureGateway sequence
   connectEngine() runs and asserts the gateway observed the DB-set value.

11 new test cases total. All pass against the production code in this
PR.

* docs(todos): follow-ups from PR #719 codex review

Three items surfaced during /codex outside-voice review of PR #719's plan
that are out of scope for the current PR but worth tracking:

- gbrain doctor: warn on misconfigured multimodal model (P2). Two checks:
  multimodal_model set without recipe API key; embedding_multimodal flag
  on without a multimodal-capable embedding_model.

- Reclassify Voyage HTTP 4xx as AIConfigError (P2, Codex F2). Today
  gateway.ts:626 throws AITransientError for any non-401/403 4xx, so
  permanent config bugs (malformed body, model not in multimodal_models)
  trigger retry storms. Aligns with normalizeAIError's contract.

- gbrain config unset <key> (P3, Codex F6). Once a user sets a key in DB
  there's no normal CLI path to clear it. Pre-existing UX gap; PR #719's
  new key surfaces it again.

* chore: bump version and changelog (v0.28.11)

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs: v0.28.11 annotations for ai/types, ai/gateway, voyage recipe

Updates the Key Files section so the per-file annotations reflect the
multimodal_model routing + model-level validation that landed in #719.
