Key change: replace CCCL 3.6 types with corex CUB equivalents
- cuda::std::plus<> → cub::Sum
- cuda::maximum<> → cub::Max
- Remove #include <cuda/std/functional>
Test results from real machine (3/4 passed):
✓ __shfl_down_sync works on ivcore10
✓ manual SMEM+shuffle block reduce works
✓ corex CUB cub::BlockReduce<float,256> compiles and runs correctly (32640)
✗ CCCL 3.6 variadic function issue — corex clang rejects device variadic
Confirmed: use /usr/local/corex/include/cub/ for all kernel code
cccl_upstream is reference only, NOT compilable on corex
