refactor: migrate from KuzuDB to LadybugDB v0.15 (#275)
* 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* chore: remove outdated KuzuDB migration brainstorming document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
