tools.chromadb_tools module

Vector database management tools (Postgres + pgvector).

Admin tools for creating ad-hoc vector databases. Each database is a Postgres schema vdb_<name> containing a single items table (halfvec(3072) + HNSW). Embeddings are computed with Gemini 3072-d via the shared embed pool. (The module name is retained for back-compat; the ChromaDB backend was replaced by pgvector.)
