Understanding

Add [tool.mypy] configuration to pyproject.toml to ensure clean type checking across all 13 source files in src/.

Execution plan

1. Add [tool.mypy] section to pyproject.toml.
2. Verify with python -m mypy src/.
3. Add tests/test_wheel_build_and_cli.py for standalone CLI execution.

Actual changes

• pyproject.toml: added [tool.mypy] with python_version = "3.10", mypy_path = ["src"], explicit_package_bases = true.
• tests/test_wheel_build_and_cli.py: added CLI execution tests.

Blockers

• None. Mypy passes with 0 errors across 13 source files.
