Minimal Prometheus + Grafana stack that scrapes the metrics written by the cleanup script.

• docker-compose.yml — Prometheus, node-exporter (textfile collector), Grafana
• prometheus.yml — scrape configuration
• grafana/provisioning/ — auto-provisioned Prometheus datasource and Infra-Guard Overview dashboard

docker compose up -d

• Prometheus: http://localhost:9090
• node-exporter: http://localhost:9100 (exposes the textfile metrics)
• Grafana: http://localhost:3000 (defaults to admin/admin, override with GRAFANA_USER/GRAFANA_PASSWORD)

The cleanup script writes textfile metrics to monitoring/textfile/infra_guard.prom (default of --metrics-file). node-exporter serves them through its textfile collector (with default host collectors disabled, so it exposes only Infra-Guard metrics) and Prometheus scrapes them via the node job. Grafana includes the pre-provisioned "Infra-Guard Overview" dashboard displaying resource counts, cleanup health, failure tracking, and S3 sync status.
