data: complete SGEMM upstream from 3 repos (siboehm+wangzyon+edtallison) + xllm fused_qknorm_rope + xattention kernels
SGEMM repos (upstream_ref/sgemm_cuda/, 41 files):
siboehm/SGEMM_CUDA: kernel 1-12, runner, CMake, cuBLAS benchmark
wangzyon/NVIDIA_SGEMM_PRACTICE: kernel 1-7 (Chinese comments), utils
edtallison/sgemm-cuda: kernel 01-09 (learning notes), Makefile
xllm kernels (ex_engine/xllm_kernels/cuda/):
fused_qknorm_rope.cu + bind — saves 128 kernel launches/fwd
xattention/ — 6 files from upstream xllm
headers: corex_compat_utils.h, topk_last_dim.cuh
