Deducteam/lambdapi ? reverse-engineered prompt

Build me a small proof assistant called Lambdapi that works from the command line and lets me write and check proofs in the λΠ calculus modulo rewriting.

I want it to be able to load proof files, type check them, report errors clearly, and run the example files from the repo so I can see that it works. Please also make sure the basic editor support is in place for Emacs and VS Code, and that the build works cleanly from the source with the usual OCaml tooling. If there are any current setup details I need, look up the latest docs online and follow them.

It would be great if the project feels usable right away, with a simple help command, a way to run tests, and the tutorial example working end to end. Keep the implementation tidy and make sure the documentation points a new user to the right place to get started.
