Add stderr option to Chroma client initialization for better error handling

- Updated the StdioClientTransport configuration in search-server.ts to include 'stderr: ignore' for the Chroma client.
- Modified the ChromaSync class in ChromaSync.ts to also set 'stderr: ignore' when initializing the Chroma client.
