[Feature Request] Please Add Transcription Handling Support #27

While this is a good outbound call handling example, it could really use transcript handling as an option to demonstrate how best to do this on outbound calls.

I believe I've managed to get this working on my own agent by subscribing to the lk.transcription stream in the onEnter event, with a listener collecting the messages so that I can save them in the onExit event, but while this works to a degree it feels like there should be a better way to do this if all I want to do is send the transcript of a call somewhere, and I'm not sure yet how well this will handle interruptions (i.e- the call being dropped).

So yeah, it would really help if transcription support were added to this example, as it's not as clear how best to integrate this as it is with say LiveKit Meet (where I can just display the transcription as subtitles, or chat messages or whatever). An outbound agent by comparison is essentially listening to itself, so it would help to clarify the intended way to handle that.
