新增 Kimi K3 文本模型支持:复用 Kimi Linear/KDA 路径,实现 block AttnRes、latent MoE、SiTU 激活、MXFP4 expert 权重和嵌套 text_config 权重加载;同时增加可选 MoonEP backend 与 Kimi K3 XTML tool-call parser。

分支从最新 upstream/main 提取为单个提交,未包含原开发分支中的启动、压测脚本和 Hopper all-reduce 调优。

验证:K3/MXFP4/MoonEP/tool-call 单测与 CUDA 数值测试 45/45 通过,Kimi linear cache 测试 7/7 通过;2-layer K3、TP8 的 /v1/chat/completions smoke 通过(隔离现有 TP16 服务,使用 --disable_cudagraph --disable_symm_mem_allreduce --disable_flashinfer_allreduce)。Black、compileall 和 git diff --check 通过。
