-kugetsu queue enqueue "task"   # Add task to queue

+- `notified` - PM agent has picked up the task
+- `completed` - Dev agent finished, PR created
+- `error` - Timeout or failure

+Manage the queue daemon background process:
+```bash
+kugetsu queue-daemon start     # Start daemon in background
+kugetsu queue-daemon stop      # Stop daemon
+kugetsu queue-daemon restart    # Restart daemon
+kugetsu queue-daemon status    # Check if daemon is running
+kugetsu queue-daemon logs       # Show recent daemon logs
+```
+
+**Daemon Behavior:**
+1. Runs at configurable interval (default: 5 minutes)
+2. Checks if active agents < MAX_CONCURRENT_AGENTS
+3. Picks 1-N pending items (configurable batch size)
+4. Forks PM session for each picked item
+5. PM decides whether to use `start` or `continue`
