Verbesserung: Implementierung eines Protokoll-Fallbacks für die Daemon WebSocket-Verbindung

Browse Source 
Änderungen:
- Der Verbindungsaufbau des Daemon WebSockets wurde angepasst, um zuerst mit einem spezifischen Subprotokoll zu versuchen und bei Misserfolg auf eine Verbindung ohne Subprotokoll zurückzugreifen.
- Zusätzliche Protokollausgaben wurden hinzugefügt, um den Verbindungsstatus und Fehlerdetails besser nachzuvollziehen.

Diese Anpassungen erhöhen die Robustheit der WebSocket-Verbindung und verbessern die Fehlerdiagnose.
