style: format entire codebase with ruff

Applied ruff formatting to 8 files that were not properly formatted:
- benchmarks/runner.py
- examples/oolong_example.py
- examples/subprocess_repl_demo.py
- rlm/environments/subprocess_repl.py
- tests/clients/test_huggingface.py
- tests/environments/test_subprocess_repl.py
- tests/test_exceptions.py
- tests/test_registry.py

This ensures the codebase passes CI formatting checks.
