X7legendv2/Terminal-Pre-Classic ? reverse-engineered prompt

Build me a simple Python terminal app themed around the old Minecraft Pre Classic era. I want it to feel like a tiny command line system that starts with login and registration, checks user input, then drops the user into a basic terminal loop where they can type a few built in commands.

Please include the commands whoami, plasma, bit, help, time, clear, and exit. Time should show the current time and month, clear should wipe the screen, help should list the available commands, and exit should close the app cleanly. The whole thing should feel stable and polished, like a small finished release, not just a demo.

Keep the code easy to read and improve, since this project is supposed to represent an early version that grows over time. If there are older scripts in the repo, treat them like rough earlier versions and make the final usable version the main one to run. If you need to, look up current Python best practices online.
