- Fix ontology RAG pipeline: embeddings API, chunker provenance, and query concurrency
- Fix ontology embeddings to use correct response shape from embed()
API (returns list of vectors, not list of list of vectors).
- Simplify chunker URI logic to append /c{index} to parent ID
instead of parsing page/doc URI structure which was fragile.
- Add provenance tracking and librarian integration to token
chunker, matching recursive chunker capabilities.
- Add configurable concurrency (default 10) to Cassandra, Qdrant,
and embeddings query services.
