Breaking change: per-agent collections replaced by a single 'memories'
collection with metadata-based access control.
- All memories live in one collection
- 'agent' metadata tracks the creator
- 'private' (bool, default False) controls visibility
- Query returns: shared (private=False) + own private (agent=asker)
- Save endpoint accepts optional 'private' field
- Version bumped to 0.2.0
REST API for per-agent semantic memory retrieval.
- FastAPI server with /api/{agent}/save and /api/{agent}/query
- ChromaDB for persistent vector storage
- all-MiniLM-L6-v2 via sentence-transformers for embeddings
- Per-agent collections for clean separation
- Config through env vars or config.py
- .venv ready with all dependencies
