feat: add WebSocket gateway for robot connection

- RobotGateway on /ws/robot namespace (Socket.IO)
- Device JWT auth on connection (rejects invalid/missing tokens)
- Connection tracking (connectedDevices map)
- Event handlers: wake_word_detected, audio_chunk, speech_end, user_interrupt
- Helper methods: sendAudioChunk, sendStatus, sendNotification
- Status feedback: idle, listening, thinking, speaking
