Conversation
- Add native vector index wrapper and Bare binding for IdMapIndex - Expose JS and TypeScript APIs for add/search/remove/persist flows - Add qvac-fabric overlay and integration coverage for the POC
- Point qvac-fabric overlay at the production turbovec branch - Update IdMapIndex API for q8/f32 storage and .tvim v2 persistence - Expand integration coverage for q8, f32, validation, and corrupt loads
- Update qvac-fabric overlay to the TurboVec production commit. - Add q4, mmap, compact, filtered search, prepared filters, IVF, and delta log APIs. - Harden native bindings for disposal, path handling, overflow checks, and typed-array validation. - Expand IdMapIndex integration coverage for persistence, filters, IVF, mmap, delta replay/compaction, and corrupt files.

🎯 What problem does this PR solve?
embed-llamacppdid not have TurboVec CPU support for embedding vector search. Consumers could generate embeddings, but there was no in-package API for indexing vectors, searching by stable external IDs, persisting indexes, replaying incremental updates, or using TurboVec CPU search paths.📝 How does it solve it?
IdMapIndexAPI for embedding vector search.ggml-vector-index.bitWidth: 4 | 8 | 32.uint64external IDs.addLogged,removeLogged,loadWithDelta, andcompactDelta.dispose()for indexes and filters.qvac-fabricoverlay to the TurboVec CPU-capable commit.🧪 How was it tested?
