Consolidate onto PostgreSQL by using pgvector instead of a separate ChromaDB instance. This removes a Docker volume, a large dependency, and simplifies the stack without meaningful performance impact at our document scale. - Swap langchain-chroma for langchain-postgres (PGVector) - Use pgvector/pgvector:pg16 Docker image with init script - Lazy-initialize vector store to avoid eager DB connections - Add SQL helpers for stats/delete/list (replacing _collection access) - Remove legacy main.py, chunker, petmd scraper, and /api/query endpoint Re-index required after deploy (POST /api/rag/index + /index-obsidian).
