alebcay/awesome-shell ? reverse-engineered prompt

Build me a clean GitHub style awesome list for shell tools and resources, like the README in this repo, with sections for different shells, command line productivity, customization, developer tools, system utilities, downloading, multimedia, applications, games, package management, script development, and guides.

I want it to feel like a well maintained curated reference, not a blog post. Keep the structure simple, easy to scan, and pleasant to read. Include a strong title, short intro, a table of contents, and lots of link lists with one line descriptions. Also add links to related lists for zsh, fish, and bash, plus a contribution section and license info.

If you need to, look up current docs online so the links and descriptions are accurate. Make it look polished in Markdown, with good spacing and consistent formatting, and make sure the page works nicely on GitHub.
