Stand up a production-mirror monitoring stack in the long-lived dev contour, all on galaxy-dev-internal with no host ports (reached only via the in-repo galaxy-dev-caddy): - Prometheus scrapes backend:9100, gateway:9191, node-exporter and cadvisor (30s interval, 15d retention); Loki (7d) + promtail (Docker service discovery by the galaxy.stack=dev-deploy label) for logs; Tempo (3d) for traces. - Backend and gateway now export OTLP traces to Tempo over plaintext gRPC on the internal network (OTEL_EXPORTER_OTLP_INSECURE). - Grafana provisioned as code (Prometheus/Loki/Tempo datasources plus a starter dashboard), served under /grafana/ via Caddy sub-path mode; admin password from the GALAXY_DEV_GRAFANA_ADMIN_PASSWORD secret. - Expose the Mailpit capture UI under /mailpit/ (Caddy basic-auth + MP_WEBROOT) so every captured message is readable regardless of relay. - dev-deploy.yaml seeds the monitoring config to a stable, reboot- surviving host path and injects the Grafana admin secret. Per-service memory limits keep the footprint within budget. All collector config lives under tools/dev-deploy/monitoring/ for dev/prod parity.
