Subject: [PATCH] Fix: Frontend-Build-Sicherung + Auto-Rebuild bei fehlendem
 manifest.json
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- frontend_build_quiet: altes public/build/ als .bak sichern,
  bei npm-Fehler wiederherstellen → Site bleibt immer erreichbar
- fix_permissions: wenn manifest.json fehlt, automatisch neu bauen
  → kein manueller Eingriff nach fehlgeschlagenem Update nötig
