Wrap redis-py's get_protocol_version to catch AttributeError when ClusterPipeline objects lack nodes_manager attribute. Returns None on error, causing NEVER_DECODE to be set (safe fallback behavior).
This fixes crashes when using SearchIndex.load() with Redis Cluster where batch operations create ClusterPipeline objects internally.
Fixes #365
