Major observability stack migration:
- Deploy Prometheus in k8s with 20Gi PVC, Tailscale Ingress
- Deploy Loki in k8s with 20Gi PVC, Tailscale Ingress
- Update Grafana to use k8s-internal endpoints for data sources
- Update Alloy on indri to push to k8s via Tailscale endpoints
- Prometheus scrapes sifaka via LAN IP (Docker NAT, same as NFS)
- Deprecate ansible prometheus/loki roles
Alloy on indri continues to collect:
- System metrics (via prometheus.exporter.unix)
- Textfile metrics (borgmatic, plex)
- Logs (forgejo, tailscale, borgmatic, zot, plex)
