AlertManager gains an optional openclaw_client. check_alerts records
each newly created alert and AlertManager.maybe_autoscale (called
from the async router for each alert) invokes cron_pool.scale_up(1).
scale_up itself caps at MAX_POOL_SIZE so repeated invocations are safe.
Removed the xfail guard in test_alert_autoscale_link; rewrote the test
to use task_backlog (duration_minutes=0) so a single check_alerts call
fires an alert and triggers auto-scale.

- Add alerts.py with alert rules (pool utilization > 90%, task backlog > 50, stuck rate > 10%)
- Implement alert history and webhook notifications
- Add metrics and alerts APIs
- Add database migration for alert history table
- Add 11 unit tests for metrics, 10 unit tests for alerts, 8 integration tests
