- Added @chroma-core/default-embed dependency for local embeddings
- Updated ChromaSync to use DefaultEmbeddingFunction with collections
- Added isServerReachable() async method for reliable server detection
- Fixed start() to detect and reuse existing Chroma servers
- Updated build script to externalize native ONNX binaries
- Added runtime dependency to plugin/package.json
The embedding function uses all-MiniLM-L6-v2 model locally via ONNX,
eliminating need for external embedding API calls.

- Updated chromadb from ^1.9.2 to ^3.2.2 (includes CLI binary)
- Changed heartbeat endpoint from /api/v1 to /api/v2
The 1.9.x version did not include the CLI, causing `npx chroma run` to fail.
Version 3.2.2 includes the chroma CLI and uses the v2 API.

Replace MCP subprocess approach with persistent Chroma HTTP server for
improved performance and reliability. This re-enables Chroma on Windows
by eliminating the subprocess spawning that caused console popups.
Changes:
- NEW: ChromaServerManager.ts - Manages local Chroma server lifecycle
via `npx chroma run`
- REFACTOR: ChromaSync.ts - Uses chromadb npm package's ChromaClient
instead of MCP subprocess (removes Windows disabling)
- UPDATE: worker-service.ts - Starts Chroma server on initialization
- UPDATE: GracefulShutdown.ts - Stops Chroma server on shutdown
- UPDATE: SettingsDefaultsManager.ts - New Chroma configuration options
- UPDATE: build-hooks.js - Mark optional chromadb deps as external
Benefits:
- Eliminates subprocess spawn latency on first query
- Single server process instead of per-operation subprocesses
- No Python/uvx dependency for local mode
- Re-enables Chroma vector search on Windows
- Future-ready for cloud-hosted Chroma (claude-mem pro)
- Cross-platform: Linux, macOS, Windows
Configuration:
CLAUDE_MEM_CHROMA_MODE=local|remote
CLAUDE_MEM_CHROMA_HOST=127.0.0.1
CLAUDE_MEM_CHROMA_PORT=8000
CLAUDE_MEM_CHROMA_SSL=false
