Build me a simple Linux setup script repo that I can clone and run with one command.

When I run ./setup.sh, it should detect my distro and apply the right setup automatically, with support for at least Fedora and Arch. I want it to be easy to extend later if I add more distros. It should also include a separate way to apply my git settings on their own, since I might want that without running the full setup.

Please make the script practical and straightforward, with clear output so I can tell what it is doing. If anything needs current distro specific guidance, look up the latest docs online if you need to. Keep the repo simple and organized so someone can understand it quickly, and include a README that explains how to clone the repo and run the setup.
