feat: Improve WebMCP connection handling and tools management
WebMCP service: - Add headless mode configuration - Implement proper event handlers with unsubscribe support - Add connection info tracking (channel, server, status, tools) - Add destroyWebMCP for cleanup - Improve connectWithToken to pass token directly Canvas store: - Add connection state (reconnecting, status, error, info) - Add computed statusColor for UI feedback Components: - Add ConnectionDropdown for connection status display - Add ToolsDropdown for tools management UI Tool registry: - Improve tool activation/deactivation logic - Better error handling and logging
