stumpylog f0d233631a Design: Replace FAISS vector store with LanceDB (custom adapter)
Spec for swapping the AI feature's llama-index FAISS StorageContext trio
(FaissVectorStore + SimpleDocumentStore + SimpleIndexStore) for LanceDB via
a custom BasePydanticVectorStore adapter (no llama-index-vector-stores-lancedb,
no pandas).

Covers: disk-resident memory-mapped storage, native merge_insert upsert with
when_not_matched_by_source_delete, MetadataFilters(IN) filtering on a top-level
document_id column, auto IVF ANN threshold (IVF_FLAT fallback), MVCC compaction
via optimize(cleanup_older_than=...), migration, concurrency, and testing.
