Description

CVU kernel Node that casts a tensor between FP32 and BF16 (no scale/zero-point).

Typically inserted by the route planner at the MLA boundary on the BF16 path. Application code rarely adds Cast directly — it appears via DetessCast/CastTess fusions or via planner-generated routing — but the standalone form exists for graphs that need a bare dtype conversion stage.
