v0.0.25

Fixes the video going black for a minute or two after switching away from the app and back (cursor kept moving fine, but the rest of the screen stayed dark). Switching apps rebuilds the video surface from scratch, which means a brand-new decoder with nothing to show yet — it was just sitting there waiting for the Mac's own periodic keyframe, up to 60 seconds away. It now asks the Mac for one immediately instead of waiting, the same way an actual decoder error already did. Recovery is down to a few seconds, confirmed live with a real Mac connection.
