tuiplay 0.7.28

Fixed

• Stale bold rows no longer pile up at the top of the queue after several
  track changes. Bubble Tea's line diff could leave the previous playing
  row's bold styling on screen, so the interface now forces a full repaint
  whenever the playing track changes.

Changed

• Updated the README for the current visualizer modes, Go requirement,
  configuration, key-binding limits, lyrics behavior, smart playlists,
  external control, and native audio support.
• Synchronized config.example.toml and the generated first-run template with
  all current options and actions, and corrected their zero-value semantics.
• Updated maintenance documentation to remove contradictory current-state
  guidance.
