093bfb380f feat: pybind11 bindings for xllm CUDA kernels
norm.cu compiled successfully on BI-V100 (only warning: fp8 __host__ attr).
Failed at import because no PYBIND11_MODULE — now fixed.

New bindings/ directory with 4 binding files:
  xllm_norm_bind.cpp      → rms_norm, fused_add_rms_norm
  xllm_activation_bind.cpp → silu_and_mul, gelu_and_mul, act_and_mul
  xllm_rope_bind.cpp       → rotary_embedding
  xllm_cache_bind.cpp      → reshape_paged_cache, block_copy

Build script updated: each .so = kernel .cu + binding .cpp

51cb90b9ab fix: adapt xllm norm.cu for corex CUB (CUDA 10.2)
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
