- Add AbortSignal.timeout(30s) on all fetch calls
- Add retry with backoff for 429/5xx (core: 2 retries, MCP: 1 retry)
- Guard initEmbedder() and getEmbedder() to throw in HTTP mode
- Discard cached embeddings on dimension mismatch during incremental re-index
- Add MCP embedQuery retry for transient failures
- Add 16 unit tests covering both core and MCP HTTP paths
- Fix README: concise, accurate env var docs
* refactor: migrate from KuzuDB to LadybugDB v0.15
KuzuDB was archived (Apple acquisition, Oct 2025). LadybugDB is the
community fork with full API compatibility.
- Package swap: kuzu → @ladybugdb/core, kuzu-wasm → @ladybugdb/wasm-core
- Rename all internal paths: kuzu → lbug (adapters, schema, storage)
- Storage path: .gitnexus/kuzu → .gitnexus/lbug (with auto-cleanup)
- Add explicit VECTOR extension loading (required in v0.15)
- Update CI workflow, documentation, and all tests
- 1151 unit + 27 integration tests passing

* fix: address code review findings (P1-P3)
P1: Fix WASM adapter to use getAll() API, wire cleanupOldKuzuFiles
into analyze command, add symlink path traversal protection.
P2: Cache VECTOR extension load state, batch augmentation engine
queries (20→4), fix web getCopyQuery for multi-language tables,
fix stale KuzuDB references, correct brainstorm package names.
P3: Complete lbug-wasm.d.ts type declarations, batch semantic
search per-label, update stale BM25 comment.
* chore: remove outdated KuzuDB migration brainstorming document
* fix: load FTS extension in MCP pool adapter on init
The read-only pool adapter never loaded the FTS extension, so all
QUERY_FTS_INDEX calls failed silently. This broke search-pool and
augmentation integration tests, and caused empty results in the
web UI server mode.
* feat: implement shared Database caching and connection reference counting
* feat: enhance KuzuDB migration handling and status reporting
* fix: mock cleanupOldKuzuFiles in local backend callTool tests
* fix: update mock for cleanupOldKuzuFiles and adjust imports in callTool tests
