Research direction

Start by locating the SM3 implementation and the vsm3* intrinsics, then inspect how the neon and sm4 target features are gated. The issue names no files or tests, so identify the existing backend and validation path before making changes. Done means ARM targets can use the hardware-accelerated SM3 backend without breaking the existing implementation.
