feat(daemon): add WebSocket relay with console/network monitoring

- Add ws-relay.ts: WebSocket server at /ws with broadcast function
- Add network event types (request/response/failed) to core ws.ts types
- Add ConsoleEntry and NetworkEntry types
- Add consoleLog and networkLog buffers to PageRegistry (100/200 max)
- Add console listener in createPage: broadcasts page:console events
- Add network listeners (request/response/requestfailed) in createPage
- Add page crash handler broadcasting page:crashed events
- Add history endpoints: GET /pages/:id/console and GET /pages/:id/network
- Integrate createWsRelay in server.ts startup
- Bump ws from devDependency to full dependency
