course-to-appimage

From the author

Package an existing interactive course generated by the book-to-course skill (a folder with index.html, assets/ and course/data.js, or its .zip) into a self-contained Linux AppImage — one file that carries its own WebView engine (Electron), so it runs on any desktop distro without installing anything, keeps progress in a file and can run code exercises' tests. Checks the build tools on the machine (appimagetool, Electron, AppImage runtime), tells the user exactly what is missing and where to get it, and can download it for them. Use this whenever the user wants a course "na Linuxa", "jako aplikację na pulpit/desktop", "w menu aplikacji", "zrób z kursu AppImage", "course to appimage", wants a course app they can copy to another Linux computer, wants to open their generated course like a normal program instead of start.sh, or wants to rebuild/update the course app after adding chapters — even if they don't say "AppImage" explicitly. Do NOT use for building a course from a book (that is book-to-course), for Andr
