chore(cartridge): skip formatting on auto-generated code (#267)

The code generated under [`cartridge/src/controller.rs`] may not comply with the formatting expected by [`rustfmt`]. This can trigger false positives and unnecessary diffs when running formatting checks.

Instead of enforcing formatting, we exclude the file entirely since the code may be rewritten on every build, making formatting noisy.
