v0.5.0 Status GUI

This is the first release to include a GUI. Presently it just shows a system tray icon and displays when recording has started or stopped when using the realtime API. This provides visual feedback as to whether VoxInput is active and responding to input.

It doesn't yet show when VAD detects speech, this requires enhancements to LocalAI.
