Pull request overview

This PR adjusts the functional test framework’s swap_directory() helper to better support model reload scenarios by ensuring the target directory’s parent path exists before attempting a directory swap.

Changes:

• Create the target_path parent directory (if needed) before renaming staging_path into place.
• Simplify rollback logic in the error path by removing the target_moved flag and relying on old_path existence.
