Add full Pi 5 satellite setup with ReSpeaker 2-Mics pHAT for kitchen
voice control via Wyoming protocol. Includes satellite_wrapper.py that
monkey-patches WakeStreamingSatellite to fix three compounding bugs:
- TTS echo suppression: mutes wake word detection while speaker plays
- Server writer race fix: checks _writer before streaming, re-arms on None
- Streaming timeout: auto-recovers after 30s if pipeline hangs
- Error recovery: resets streaming state on server Error events
Also includes Pi 5 hardware workarounds (wm8960 overlay, stereo-only
audio wrappers, ALSA mixer calibration) and deploy.sh with fast
iteration commands (--push-wrapper, --test-logs).
