Jeetkumarsahu/skyping — reverse-engineered prompt

Build me a simple Linux app called Skyping that lets two people share a terminal session directly, kind of like screen sharing but for the command line. I want one person to be able to start a session and get a short code or link, and the other person can join from another Linux machine and see the same terminal in real time. It should feel lightweight and easy, good for remote help, pairing, or demos.

Please make the basic flow clear from the command line, like host a session, join a session, and end it cleanly. If there needs to be a small relay or coordination service to help the two sides connect, include that too, but keep the user experience simple. It would be great if it works well over the internet, not just on the same network, and if there is a Docker option for the server side. Add a short setup guide and usage examples since there is no real README yet. Look up current docs online if you need to.
