Test 10e6d7b366 fix: handle EADDRINUSE in MCP server ws-bridge — allow Claude Code to start when port is taken ...

When Claude CLI starts the Laputa MCP server, it crashed immediately because
startUiBridge() tried to bind port 9711 which is already held by the running
Laputa app. The unhandled EADDRINUSE error killed the process, making all
Laputa MCP tools unavailable to Claude Code in AI Chat.

Fix:
- Make startUiBridge() async, return Promise<WebSocketServer|null>
- Handle 'error' event on HTTP server: EADDRINUSE resolves to null instead of crashing
- Guard broadcastUiAction() with 'if (!uiBridge) return' for graceful no-op
- In ws-bridge.js main: chain startUiBridge().then(() => startBridge())

All vault tools (read/write/search) now work via stdio MCP when port is busy.
