Remove local_files_only from transformer load to fix missing snapshots/

The bucket has the V23 blobs (19 GB) but no snapshots/ directory, so
local_files_only=True caused a silent hang because HF cache couldn't
resolve filenames to blobs. Without the flag, HF fetches the manifest
from Hub (fast metadata call), creates the snapshots/ symlinks against
the existing blobs (no re-download), then loads normally.
