2026-04-16Add /metrics Prometheus endpoint to daemon modePaul Buetow
Exposes a gauge per host tracking the Unix timestamp of the last records file update. Excluded hosts (from the excluded_host table) are labeled excluded="true" so alerting rules can filter them out. Uses manual Prometheus text format to avoid adding a new dependency. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
