when a folder has mixed audio/subtitle layouts, the mismatch banner now offers a toggle: convert the matching group (pick tracks, skip the rest) OR convert every video keeping all audio + all subtitles (no picking, nothing skipped). the second mode hides the pickers and clears the track-selection inputs so run.sh keeps everything. only shown for tasks with track pickers (Convert Video).
