librespot 0.7+ unterstützt --password nicht mehr (nur noch OAuth/Zeroconf). Der --password-Arg ließ librespot sofort abstürzen → leere Pipeline. - username/password aus config.yaml und run.sh entfernt - librespot nutzt jetzt ausschließlich Zeroconf/mDNS zur Erkennung - Gerät erscheint automatisch in der Spotify-App im lokalen Netz Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
