fix artwork race, chat-only disposal, and stall recovery in pip

- Fix Now Playing artwork: controller's mediaInfo field is now mutable
  so setMediaInfo updates it before loadUrl sends to native. Bumps fork
  which also merges artworkUrl on the native side as defense-in-depth.
- Pause native player in chat-only mode via showVideo reaction. Cancels
  latency/stall timers and aborts in-flight loads when video is hidden.
- Remove PiP-specific stall recovery path — light refresh preserves the
  PiP window, so PiP can use the same escalation ladder as normal play.
- Fix stale _initInFlight clobber on generation mismatch early-return.
- Reset _streamQualityIndex on refresh to avoid stale quality label.
- Thread-safe hasActivePlayers on SharedPlayerManager (fork).
