Add instructions on how to use Circuzz with Noir in README.md

[Savio-Sou]

There is currently some descriptions of how to use Circuzz with Circom in the README, but none on other ZK technology stacks that Circuzz also supports.

It'd be great to add detailed instructions on how to use Circuzz with Noir to the README.

Hello @Savio-Sou,

Thanks for the feedback!

The README does cover the setup for all four systems, including Noir. It’s not just about Circom. If something felt unclear or missing, let us know what exactly you were expecting. Maybe we can make it clearer, but it would help to know what part was confusing.

Ah maybe I was skimming through it too quickly 🙏

I was reading the Building A Podman Image and Running A Single Metamorphic Test sections that only reference Circom images and command flags. It wasn't immediately intuitive to me how can I use Circuzz with Noir.

The Podman parts are mostly useful for tracking down specific bugs and aren't required for running the project.

If you want to use the latest version, the easiest way is to set up your own custom Docker or Podman container and copy the project into it. Make sure the noir executables (nargo, bb) are available in your environment. Running the project works the same as for circom, just be sure to select the noir backend and the appropriate config:

> python3 cli.py explore \
    --tool noir \
    --report-dir out/report \
    --working-dir out/working \
    --config res/configs/default/noir.json

Note that the latest fully tested noir version was c4273a0 with bb version 0.56.0. So it might be that some language or command reworks are not yet reflected in circuzz.

I hope this clears up some of the confusion.
