dylanyunlon 967d572073 feat: CCCL CachingDeviceAllocator LD_PRELOAD — bypass CoreX expandable_segments ASSERT

从 CCCL upstream cub/cub/util_allocator.cuh 提取 CachingDeviceAllocator
核心算法，去掉所有 CUB/CCCL 宏依赖，编译为独立 .so。

用 LD_PRELOAD 拦截 cudaMalloc/cudaFree，路由到 CUB 的 geometric-bin
缓存分配器。同时在 constructor 中 strip PYTORCH_CUDA_ALLOC_CONF 里的
expandable_segments 配置，避免 CoreX CUDACachingAllocator.cpp:545 ASSERT。

BI-V100 调优参数:
  bin_growth=8, min_bin=3 (512B), max_bin=13 (~550MB)
  max_cached_bytes=4GB per device (32GB卡的合理上限)

真机测试步骤:
  1. bash build_cccl_preload.sh
  2. LD_PRELOAD=./libcccl_allocator.so CCCL_ALLOC_DEBUG=1 \
     PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True \
     python3 verify_preload.py
