Función del grupo fleet-metrics que convierte la respuesta JSON del endpoint /healthz de un nodo unibus (membershipd) en series Prometheus (unibus_up, unibus_status_ok, unibus_posture_enforce/acl/tls/cluster, unibus_store_kv) con labels node/instance. Pura de transformación (impure solo por el error de unmarshal). La consume el daemon unibus_exporter del project fleet_monitoring. Con tests golden/edge/error.
