* Add .worktrees/ to .gitignore

* feat: add cert-manager alerting rules (4 rules)

Add Prometheus alerting rules for cert-manager under the
"Network, security and storage" category:
- Cert-Manager absent (service down detection)
- Certificate expiring soon (21-day threshold)
- Certificate not ready (readiness check)
- Hitting ACME rate limits (rate limit detection)

Based on imusmanmalik/cert-manager-mixin and official
cert-manager metrics documentation.

* docs: add cert-manager to README
