Add /metrics Prometheus endpoint to daemon mode
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.
