Add autoplay, progress rings, duplicate-lesson detection, title-card thumbnails
- Auto-play next lesson on end, with a cancelable countdown and a Settings toggle (default on). - Grid-view course cards show a small progress ring (checkmark at 100%) instead of a separate bar. - Duplicate Lesson Files: scans within each course/folder for media files that look like the same lesson downloaded twice, with per-file delete and a shared ignore list with Duplicate Courses. - Auto-generated cover art now samples a few early candidate frames and keeps the largest JPEG, favoring an intro title card over a blank fade-in or a plain presenter frame. - Settings -> "Regenerate Thumbnails" re-runs that logic for every course with an auto-generated thumbnail (never touches manual covers), so already-cached thumbnails can pick up the improvement. - Add .gitignore for __pycache__/.
