+Registry for device copy ops used to insert explicit H2D (host-to-device)
+and D2H (device-to-host) data transfer operations at delegate boundaries.
+
+These ops are inserted by PropagateDevicePass when enable_non_cpu_memory_planning
+is True, making the graph functional by explicitly transferring data between
+CPU and device memory.
+
+Follows the same registration pattern as dim_order_ops_registry.py.
