EnthusiastAnon/NETFLIX-DL-6.0 ? reverse-engineered prompt

Build me a simple command line tool for downloading and packaging videos I’m allowed to access, with options for video quality, output folder, season and episode selection, audio and subtitle language choices, and an option to keep or delete the temporary files after it makes the final MKV.

It should be easy to run from the terminal, show helpful usage text, and let me choose whether to download video, audio, subtitles, or any mix of them. If it helps, look up current docs online for any libraries you need, then wire it up so the download and muxing flow feels smooth and reliable.
