…allelLinear 修改文件： 1、新增`include/infinicore/ops/linear_allreduce.hpp`，用于声明 linear_allreduce() / linear_allreduce_() 融合算子接口 2、新增`src/infinicore/ops/linear_allreduce/linear_allreduce.cc` （1）设备分发：Ascend → aclnn 内核，其他平台 → linear()+allreduce() 回退 （2）非 Ascend 厂商（NVIDIA/MetaX/Moore 等）行为不变 3、新增`src/infinicore/ops/linear_allreduce/linear_allreduce_ascend.cc` （1）调用 aclnnMatmulAllReduce CANN API（F16/BF16 支持，F32 退回原始路径） （2）实现 per-stream WorkspacePool：首次分配后复用，减少malloc/free/sync开销

修改文件：
1、新增
include/infinicore/ops/linear_allreduce.hpp，用于声明 linear_allreduce() / linear_allreduce_() 融合算子接口。2、新增
src/infinicore/ops/linear_allreduce/linear_allreduce.cc（1）设备分发：Ascend → aclnn 内核，其他平台 → linear()+allreduce() 回退；
（2）非 Ascend 厂商（NVIDIA/MetaX/Moore 等）行为不变。
3、新增
src/infinicore/ops/linear_allreduce/linear_allreduce_ascend.cc（1）调用 aclnnMatmulAllReduce CANN API（F16/BF16 支持，F32 退回原始路径；
（2）实现 per-stream WorkspacePool：首次分配后复用，减少malloc/free/sync开销。
