chore: update .gitignore and pre-commit configuration; refactor CLI argument handling

- Added 'megalinter-reports/' to .gitignore to exclude MegaLinter report files.
- Configured a new pre-push hook for MegaLinter using Docker to ensure code quality checks before pushing.
- Refactored CLI command functions in cli.py to use a placeholder for unused arguments, improving code clarity.
- Adjusted test discovery path in __main__.py for consistency.
- Added pylint disable comments for import positioning in test files to address linting issues.

These changes enhance the development workflow and maintain code quality standards.
