Add patent (#334)

<!-- Thanks for making Ratatui awesome! 🐭 -->

* Link to your project (GitHub/crates.io):
https://github.com/r14dd/patent (crate: https://crates.io/crates/patent)

* Description (optional): A prior-art search for dev-tool ideas. You
give it a plain-English idea, it searches 11 package registries and
tells you if something like it already exists, ranks the matches
locally, and writes a scoped verdict. Interactive ratatui TUI, or
--json.

* Screenshot or gif (strongly recommended): [<!-- drag & drop or link
