Pull Request Overview

This PR fixes a cache issue that occurs after renaming directories. When a directory is renamed and a new directory with the same name is created, the old cached data would still be displayed instead of the new directory's contents.

Key changes:

• Added cache clearing logic after directory rename operations to prevent stale cache data
• Applied the fix to both driver.RenameResult and driver.Rename code paths
