v0.7.28

Fixed

• Audio-cleanup remux failed with dimensions not set / Could not write header (exit 234) on files with PNG/MJPEG cover art. The remux command mapped video with -map 0:v? (all video streams), which sweeps in attached-pic cover-art streams that the matroska muxer can't write a header for. Changed to -map 0:v:0? (first real video stream only), matching what the convert path already does. Cover art is dropped from the remux output, same as the convert path's deliberate behavior.
