Monitoring worker setup

1. Domain ownership is verified once per domain with TXT or CNAME at _errornotifier-challenge.<domain>.
2. Monitors wait in pending DNS verification until their domain proof succeeds.
3. Website tests support GET, HEAD, POST, PUT, PATCH, DELETE, OPTIONS, custom safe headers, and POST/JSON bodies.
4. Use WP-CLI for production checks: wp errornotifier run-checks --limit=50.
5. Use WP-CLI for queued DNS proof checks: wp errornotifier verify-domains --limit=50.
6. Windows Task Scheduler can call studio wp or wp-cli every minute with the site --path.
7. Linux cron can call: * * * * * cd /path/to/wordpress && wp errornotifier run-checks --limit=50.
8. WP-Cron is registered as a fallback only; do not rely on page views for production monitoring.
9. Cleanup command: wp errornotifier cleanup.
