- New Features - Introduce `-a` flag for autoplay mode that automatically plays the next video. - Remove unused GUI handling (`-g`/`-r`) and update dependency comment. - Enhancements - Simplify flag parsing by adding `a` to `optstring` and consolidating logic. - Replace `isGui` toggle with `autoplay` state management. - Bug Fixes - Fix index tracking in autoplay to correctly continue after manual selection. - Ensure proper termination of playlists when reaching the end.
