rust-unofficial/awesome-rust ? reverse-engineered prompt

Build me a simple Rust project that keeps a big curated list of Rust tools and resources organized in one place.

I want it to be easy to add new entries under categories, keep the table of contents updated automatically, and check that links and markdown formatting are valid. The end result should feel like a polished awesome list, with clear sections for applications, development tools, libraries, and resources.

Please make it straightforward to maintain, so someone can open it, add a new project, and not break the structure. If there’s a better way to organize or validate the list, go ahead and set that up, and look up current docs online if you need to. Also include clear contribution guidance so other people can help keep the list fresh.
