chore: migrate to ruff (#4305)

* 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
