How to set up and validate locally

1. Checkout this branch:

   git checkout roughcheck

2. Install dependencies:

   pip install pre-commit ruff

3. Install pre-commit hooks:

   pre-commit install

4. Run pre-commit on all files:

   pre-commit run --all-files

5. Make a test commit to verify Ruff runs automatically:

   git add . git commit -m "Test pre-commit Ruff"

Ruff should automatically format files and fix lint issues before the commit is completed.
