OPPO's PhoneWindowManager sets IsQuickLaunchSupport=false for apps with
VoiceInteractionService, blocking long-press power button from triggering
the assistant. Disabling the service makes OPPO fall back to the standard
ACTION_ASSIST intent path (same as App Manager).
- Disabled ClawdbotVoiceInteractionService and SessionService
- MainActivity now handles ASSIST intents directly
- Tested working on OnePlus 13 (ColorOS)
