Regenerate project map artifacts across backend, docs, openspec, and
root to refresh role descriptions and architectural notes after recent
service-registry and observability changes.
Co-authored-by: el Gentleman <gentleman@pi.local>
- 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.
