feat: FRIDAY Voice stack on the GPU machine; VoiceCoach history

FRIDAY Voice (speaches GPU STT/TTS + hermes agent + push-to-talk console) on
.150 Docker Desktop, fronted by coach.hobbs.farm. Also captures the VoiceCoach
compose/agent trees and deploy notes it replaced, which had never been committed.
