@jhheider does this accomplish what you wanted?

That's pretty good, except it requires a yaml read, even if the project name is found. A better solution probably checks the names on a pass, then does a pass reading yamls to check for provides/display-names. So you don't have to open up to over 600 files unless necessary.

I could add one that returns the first and then parallelizes a bit, need a use case where it's ok to do that tho.

Even tea/cli now errors if there are multiple results for a provides search
