fix: resolve CI failures for type checking and linting

- Remove unused cast import from direct.py
- Fix timeout parameter type in test_http_client.py
- Change StringIO to BytesIO in test_file_handler.py to match expected types
- Add type ignore comments for intentional type mismatches in tests
- Add safety check for file handle close operation
- Apply code formatting with ruff
