justradical/jellyfin-rpc ? reverse-engineered prompt

Build me a small Rust app that shows what I am currently watching in Jellyfin on my Discord status.

It should check my Jellyfin account using the API, detect the media I am playing, and update Discord Rich Presence so other people can see the title, type of media, and basic progress. I want it to work for things like movies, TV episodes, music, books, and live content if possible.

Make it easy to run from my computer or a server, as long as Discord is open and logged in. Include a simple command line way to configure the Jellyfin server and login details, plus clear setup instructions and a sample config file. If you need to check current API details or Discord presence behavior, look up the latest docs online.
