refactor(musicRecognition): replace parec/ffmpeg pipeline with songrec listen fix:#3057

Browse Source 
Use `songrec listen --audio-device` instead of manually capturing audio
with parec, converting with ffmpeg, and passing to audio-file-to-recognized-song.
Drops temp file handling and simplifies the recognition loop.
