The default mcc target selection was producing kernels that could launch on some stacks but hit invalid device function on the S3000 path. This change makes the offload arch explicit and defaults it to mp_21 while keeping an override for other cards. Constraint: Must keep existing build.sh entrypoint and avoid new dependencies Rejected: Rely on mcc default arch detection | produced mismatched kernels on this machine Confidence: high Scope-risk: narrow Reversibility: clean Directive: If you benchmark on a different MUSA card, set MUSA_TARGET_ARCH explicitly before changing this default Tested: CMake configure emits explicit offload arch flag on S3000 branch Not-tested: Cross-card behavior on non-S3000 devices
