* base requirements * autofix * Configure ruff for Python linting and formatting - Set up minimal ruff configuration with basic checks (E, W, F, I) - Add temporary ignores for common issues during migration - Configure pre-commit hooks to use ruff with pass_filenames - This enables gradual migration from black to ruff * Delete sdj * autofixed only * migrate lint action * more autofixed * more fixes * change precommit * try changing the hook * try this stuff
