feat: improve meeting mode trigger to detect speech as fallback

Browse Source 
Meeting mode auto-start now triggers on system audio energy OR speech
detection (VAD). Fixes issue where Electron-based apps like Nextcloud
Talk were not triggering recording because ScreenCaptureKit didn't
capture their audio reliably. Also improved debug logging.
