fix: resolve Python packaging issues with hyphens in project slugs

- Fixed template directory structure to use underscores for Python modules
- Updated all import statements to use underscore-based module names
- Fixed class name generation to handle hyphens correctly
- Renamed src/{{cookiecutter.project_slug}}/ to src/{{cookiecutter.project_slug.replace('-', '_')}}/
- Updated test files to import from underscore-based modules
- Fixed pytest configuration to avoid template directory collection issues
- Ensured generated projects with hyphens can be installed and run correctly

This resolves entry point errors when generating projects with hyphens in the slug,
such as 'test-package-full-quality', making them installable and functional.
