Remove dead 'currentVolume' variable that was never written to, causing SwitchDevice to always restore volume to 0 after switching audio devices. - Remove currentVolume from package state - SwitchDevice now sets mix.MAX_VOLUME after reopening device - GetVolume128 now queries SDL directly instead of reading stale variable - Add unit tests for parseSinks, parseSinkLine, and ConvertVolume - Add changelog.txt tracking all audio bug fixes
