Reject invalid API keys even when authentication is optional and add
OPTIONS handlers for batch and file routes to support CORS preflights.
Also recover orphaned batches stuck in finalizing after restarts,
include finalizing in pending batch queries, preserve multipart upload
content handling, and fetch remote vision images as data URIs for
Anthropic requests.
* feat(vision-bridge): add automatic image description fallback for non-vision models
Implements VisionBridgeGuardrail (priority 5) that intercepts image-bearing
requests to non-vision models, extracts descriptions via a configurable
vision model (default: gpt-4o-mini), and replaces images with text before
forwarding. Fails open on any error.
- Add VisionBridgeGuardrail class extending BaseGuardrail
- Add visionBridgeHelpers: extractImageParts, callVisionModel, replaceImageParts, resolveImageAsDataUri
- Add visionBridgeDefaults with configurable settings
- Register VisionBridgeGuardrail in GuardrailRegistry at priority 5
- Add 51 unit tests covering all spec scenarios (VB-S01 through VB-S10)
- Dependency injection for getSettings and callVisionModel (testable without SQLite)
