Based on the git diff showing extensive package-lock.json changes and modifications to the agent system prompt and configuration, here's the commit message:

```
feat: add AI SDK dependencies and refine agent voice interaction config

- Add @ai-sdk packages for enhanced AI capabilities
- Install Deepgram SDK, livekit-client, and werift for voice/WebRTC
- Expand agent system prompt with multi-tool workflows and Claude Code interaction patterns
- Adjust VAD timing (1.2s silence threshold) and turn detection for better voice UX
- Switch TTS to inworld/inworld-tts-1 with Olivia voice
- Configure interruption timing (0.2s detection, no word requirement)
- Add comprehensive guidelines for conversational responses vs structured output
- Document plan mode triggers and Claude response type handling
