Description

Turns out to use print bypassing nargo we just need to bring in the part of stdlib correctly declaring print oracle harnesses.

huh, the fuzzing test doesn't seem to be a flake here. Not sure why it's seeing two imports of print.

I thought maybe we could use StdLibAssets to avoid having to duplicate the code, but the print code is mixed into the top library 🫤

Maybe it could be separated into its own .nr file and exposed as pub use, and then we could just include that file.

I think the reason it fails is because comptime_vs_brillig_nargo adds print on its own, while comptime_vs_brillig_direct doesn't, for some reason.

So this doesn't need to happen for the traditional comptime fuzzing where it already worked, just the direct one, which bypasses certain steps. Maybe not loading the standard library is on of the things that makes it faster.
