- Added `move` operation to `Directory` to rename files and
directories within the same directory. This improves
file management capabilities.
- Updated `VFS` interface to include `move` function with
FSEntry return type for consistency. This allows for
retrieving metadata of the moved file/directory.
- Implemented `move` operation for `LocalVFS`, `OurDBVFS`, and
`NestedVFS`. This provides consistent file move
functionality across different VFS implementations.
- Added tests for the new move functionality in
`vfsourdb_test.v`. This ensures the correct behavior of the
new feature.
