        This PR syncs the version update from the release branch back to the dev branch.
        
        **Changes:**
        - Updated VERSION file to next development version
        - Updated project files with new version
        - Updated version header file
        
        This ensures the dev branch stays in sync with the latest version information.
        
        **Note:** This PR should be merged after the release is created.
