Proxy

A Go service that takes UDP audio-stream handling off Hannah Core.

When a Proxy connects to Core (RegisterProxy, a bidirectional keep-alive gRPC stream), Core disables its own UDP server entirely — all satellite audio then flows through the Proxy instead. Go's concurrency model suits that job well; the Proxy hands Core clean PCM audio (SubmitSatelliteAudio) rather than Core having to juggle raw UDP packets itself. If the Proxy disconnects, Core re-enables UDP automatically.

The Proxy also relays satellite connect/disconnect events (NotifySatelliteRegistered / NotifySatelliteGone) and receives PlayAudioCommands pushed back from Core over the same stream for TTS playback.
