denisidoro/navi ? reverse-engineered prompt

Build me a terminal app called navi that helps people find and run command line cheatsheets without needing to remember every option. I want it to let someone browse a library of cheatsheets, search for the command they need, see short descriptions and example snippets, and fill in missing values with helpful suggestions before running the final command.

It should work nicely from the command line, and also feel good as a shell widget so the real command goes into shell history, not just the launcher. Let users keep cheatsheets in a local folder, import them from other repos, and create their own simple cheatsheet files. Support the common interactive picker experience people expect, and make the interface clean and easy to use in a terminal.

If anything is unclear, check the current docs online and keep the implementation practical and polished.
