Heartbeat Integration

ClawdScan can run automatically as part of Clawdbot's heartbeat system:

### In HEARTBEAT.md
- Check session health every 6 hours
- Alert if >5 bloated sessions found
- Alert if total usage >100MB
- Auto-cleanup zombies (if enabled)

Heartbeat Configuration

{
  "heartbeat": {
    "enabled": true,
    "interval": "6h",
    "auto_cleanup": false,
    "alert_thresholds": {
      "bloated_sessions": 5,
      "total_size": "100MB"
    }
  }
}
