Check mode gate

Run the formatter with --check or --diff in CI so unformatted code fails instead of being rewritten.

How to build it

Add a CI job that runs the formatter in check mode, such as --check or --diff.
Make the job fail on any drift and print the diff in the log.
Run the same command in the pre-commit hook so contributors see the failure first.

A CI step running ruff format --check, prettier --check, biome format --check or cargo fmt -- --check.
A workflow job that exits non-zero on unformatted files.
A pre-commit hook configured with the same formatter arguments as CI.
