知音 0.1.0

First public release.

• A daily edition: your likes split into stations, each with a handful of picks and one line on why.
• Picks are judged on fit and on the recording itself. Fewer go out when the editor isn't sure.
• Ask for music in your own words.
• Player with synced lyrics (word by word where available, translations, romanization), crossfades, media keys,
  a mini window and an immersive view.
• "Your ear": every like on one record, by year and by station, with a written portrait of your taste.
• Invite a friend or two; each connects their own YouTube Music through Google, and likes sync back.
• Runs on a Mac, or on a small server with the audio model on a Mac worker.
