This change broadens the hardcoded list of album art filenames the script recognizes, adding common variants like folder.* and AlbumArtwork.* alongside existing cover.* names. It improves media notification behavior for libraries that don't standardize on a single cover filename, reducing cases where artwork is missing even though an image is present. Practical effect: more playback notifications should now show album art out of the box.

Expanded album art filename detection in notify-send.lua so notifications pick up more common cover image conventions. - zhengqunkoo/mpv-notify-send
