Etappe 2: Ripping-Pipeline — Erste Implementierung

- DockerfileWorker: abcde, flac, ffmpeg, handbrake-cli installiert
- ripping.py: Ripping-Module für DVD/Blu-ray mit HandBrake
- tasks.py: Disc-Typ-Erkennung + passendes Ripping-Modul
- docker-compose.yml: Output-Verzeichnis /output hinzugefügt
- output/ Verzeichnis erstellt

WIP: CD-Ripping mit abcde noch nicht implementiert
