Add complete CCCL CUB header tree (1394 files) to cccl_preload/include/: - cub/device/ — DeviceRadixSort, DeviceScan, DeviceHistogram, DeviceReduce, DeviceSelect - cub/agent/ — all agent implementations (sort, scan, reduce, histogram, etc) - cub/block/ — BlockScan, BlockReduce, BlockExchange, BlockLoad, BlockStore, etc - cub/warp/ — WarpScan, WarpReduce, WarpExchange, WarpMergeSort - cub/thread/ — thread-level operators - thrust/ — sort_by_key, iterator utilities - cuda/ — execution, stream, memory_resource, functional New kernel: cccl_moe_sort_scatter.cu - Uses CUB DeviceRadixSort::SortPairs to sort (expert_id, token_idx) pairs - O(n) radix sort replaces O(n log n) torch.argsort in MoE prefill path - Boundary detection + fill for expert offsets/sizes - Compiled against CCCL upstream headers (not corex CUB) to avoid BI-V100 bugs Previously only 288 CCCL headers (CachingDeviceAllocator only). Now 1394 headers — full CUB device-level algorithm stack available for all future kernels.
