fix: resolve Docker stdio initialization timeout issue

Browse Source 
- Add InitializeRequestSchema handler to MCP server
- Implement stdout flushing for Docker environments
- Create stdio-wrapper for clean JSON-RPC communication
- Update docker-entrypoint.sh to prevent stdout pollution
- Fix logger to check MCP_MODE before level check

These changes ensure the MCP server responds to initialization requests
within Claude Desktop's 60-second timeout when running in Docker.
