Fix music parallelism: add youtube-music Electron app detection and use SIGKILL

- Added 'youtube-music' and 'YouTube Music' patterns to detect Electron app
- Added explicit killing of youtube-music process
- Use SIGKILL (-9) to ensure apps are actually terminated
- Fixed log function to not fail on permission errors
