Prometheus metrics (internal/metrics/, cmd/maglevd/) - New --metrics-addr flag (default :9091, env MAGLEV_METRICS_ADDR) serving /metrics via promhttp. - Gauge metrics scraped on demand via a custom prometheus.Collector: maglev_backend_state, maglev_backend_health, maglev_backend_enabled, maglev_frontend_pool_backend_weight. - Inline counter/histogram metrics updated per probe: maglev_probe_total (by backend, type, result, code), maglev_probe_duration_seconds (by backend, type), maglev_backend_transitions_total (by backend, from, to). - StateSource interface in metrics package breaks the import cycle with checker; checker.Checker satisfies it via GetBackendInfo. Integration tests - Run maglevd inside a containerlab node (debian:trixie-slim with build/ bind-mounted) instead of on the host. Eliminates port collisions with any host maglevd. - maglevc commands run via docker exec into the maglevd container. - Add 6 Prometheus test cases: endpoint reachable, all backends report state=up, probe counters non-zero, duration histogram populated, pool weights correct, transition counters present.
