Subject: [PATCH] fix: TypeScript-Fehler im Frontend beheben
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- AudioPlayer: findLast → reverse().find() (ES2022 Kompatibilität)
- ChapterList: findLastIndex → manuelles for-loop + implizit any behoben
- Library: searchDebounce Variable 't' undefined → korrekte Initialisierung
