Pull Request Overview

This PR modifies the DirectoryObject class to automatically protect folders that already exist when they are instantiated. The protected parameter now defaults to None, which means the protection behavior is determined by whether the directory exists at instantiation time.

• Changed the default value of protected parameter from False to None
• Added logic to automatically set protected=True for existing directories and protected=False for new directories
• Added comprehensive test coverage for the new protection behavior
