Play music on YouTube via browser automation with playwright-cli.
Use when the user wants to:
(1) play a specific song (e.g. 'play Money Money Money by ABBA')
(2) play songs by an artist as a playlist or mix (e.g. 'play Jay Chou's songs')
(3) play genre or mood-based music (e.g. 'play relaxing spa music', 'play 60s Chinese oldies')
(4) control playback — next, pause, resume, stop, skip ad, change song, close the player.
Also handles song/artist name corrections from voice transcription errors.
