Subtitle Auto-Sync

Aligns the current external subtitle to the audio with alass or ffsubsync in the background, then loads the synced copy saved next to the original. Manual offset keys (Alt+Z / Alt+X) are remembered per file. Uses an installed alass or ffsubsync; otherwise downloads alass on first use (3 MB on Linux x86_64, 26 MB on Windows) and, without a system ffmpeg, Vivi's media ffmpeg build (about 15 MB, shared with Chapter Thumbnails).
