Feature: Tonspur-Ergebnis sichtbar am Paket (audioStripSummary)

Die Antwort auf "warum hat Paket X noch .DL.?" steht bisher nur in den
Rename-/Item-Logs — "kein Deutsch-Tag" ist INFO-Level und taucht nirgends im
UI auf. Jetzt speichert keepGermanAudioOnlyImpl pro Paket eine Zusammenfassung
(remuxed/kept-single/ohne-DE-Tag/ffmpeg-fehlt/Fehler + bis zu 100 Datei-Details
mit Aktion, Grund und erkannten Sprachen) direkt am PackageEntry:

- Status-Spalte zeigt "Tonspur: 5 OK / 1 ohne DE-Tag / ffmpeg fehlt" (rot bei
  Auffaelligkeiten, flacher Stil), Datei-Details als Tooltip.
- Auch der ffmpeg-nicht-gefunden-Fruehausstieg schreibt die Summary.
- pkg.updatedAt wird gesetzt + Feld im Paket-Delta-Hash, damit der Snapshot
  die Aenderung pusht; normalizeLoadedSession whitelistet das Feld mit
  Shape-Validierung, sonst waere es nach jedem App-Neustart weg.
- 2 neue Integrationstests (Summary-Zaehler + ffmpeg-fehlt-Pfad).
