Success009/mcl-launcher ? reverse-engineered prompt

Build me a simple cross platform launcher called MCL Launcher that people can install quickly on Linux and Windows.

I want the project to have easy one command install scripts for Linux and PowerShell on Windows, plus a small launcher command people can run after install. Keep it lightweight and straightforward, with a clean setup flow and clear output so someone not very technical can get it working without trouble.

Please make sure the install experience feels polished, handles basic errors nicely, and gives the user a clear next step if something goes wrong. If you need to check current best practices or docs online, go ahead and do that.

I’d like the repo to be set up so it’s easy to install, run, and update, with the main Python package and the helper scripts all working together.
