- Archive the completed observability-service-registry SDD change into
openspec/changes/archive/ (delivered across 5 slices; only
jellyfin-service-registry remains active).
- Stop ignoring .pi-map.md / .pi-map.index.md so the navigation maps are
versioned alongside the code, and add the regenerated map pairs repo-wide.
Add docker-compose.observability.yml to run Grafana, Prometheus, Loki,
Alertmanager, Alloy and Node Exporter independently of Manage.
Includes a standalone Prometheus config, empty file-SD placeholder,
and runbook documentation.
