KoalaTrapLord bcf558418a fix(rag): squash all RAG/ChromaDB bugs #123–#130
Fixes critical API contract mismatch, batch_size wiring, lifespan init, failure tracking, build_meta persistence, mana_cost in embeddings, pyproject.toml deps, and adds full test suite.

Closes #123, #124, #125, #126, #127, #128, #129, #130
