feat(hooks): add pulse-monitor for token stall detection and auto-recovery

- Detect token stalls via message.part.updated heartbeat monitoring
- Support thinking/reasoning block detection with extended timeout
- Auto-recover: abort + 'continue' prompt on 5min stall
- Pause monitoring during tool execution
