The previous emitter ran a permanent while(true){delay} loop on the
viewModelScope from connect-time onward. Cheap in production but
catastrophic for any test that calls runTest's advanceUntilIdle()
after vm.connect() — virtual time never reached idle, hanging
NestViewModelTest's existing connection-state cases for ~15 minutes
before the worker timeout killed them.
Now the emitter is started lazily by onAudioLevel() and exits the
loop the first tick after rawAudioLevels empties, so an idle room
schedules nothing. The next decoded frame restarts it. Idempotent,
so the launch path doesn't need to call it any more — removed the
boot from launchConnect().
