[feat](trx-core): add AudioSource trait and RigCat::as_audio_source

Add AudioSource trait to trx-core rig module providing subscribe_pcm()
for demodulated PCM audio. Add opt-in as_audio_source() default method
to RigCat returning None; SDR backends will override to return Some(self).
Re-export AudioSource from the crate root. Marks SDR-01 complete.
