Refactor code structure and enhance documentation in main modules

- Updated `pyproject.toml` to include configuration for `ruff` linting tool.
- Improved `download_build.py` by adding a docstring to the `dowload` function.
- Refactored `__main__.py` for clarity and consistency in path handling.
- Enhanced `extract.py` with detailed docstrings for error classes and functions.
