Subject: [PATCH] Ensure AtomicWriter defaults to current directory

The AtomicWriter class now correctly defaults the directory to '.' when
os.path.dirname returns an empty string (e.g., for files in the current
directory). This prevents potential cross-device link errors when
moving the temporary file to the destination.

Modified the comment in `write_json` to reflect that this is the
permanent behavior, removing the 'FIX:' marker.
