- Remove unused import sys from scripts/run_tests.py
- Fix test config: remove testpaths (no tests dir), remove --disable-warnings conflict
- Remove redundant [tool.setuptools] section from pyproject.toml
- Update README.md Structure section to list all files
- Create tests/ directory for future tests
