 - fused_experts_impl 增加 VLLM_USE_MARLIN_W16A16_MOE fast path：首次对 w1/w2 做 Marlin pack 后缓存，避免重复 reorder；并将原始
    权重 offload 到 CPU，降低 GPU 双份驻留
  - envs 补齐环境变量 VLLM_USE_LIGHTOP_MOE_SUM_MUL_ADD
  - 更新 fuse_moe_w16a16_marlin.py 的报错提示为 VLLM_USE_LIGHTOP=1

新增环境变量开关 VLLM_V1_FAST_TOKEN_ID_COPY（默认关闭）。开启后在 CachedRequestState 中缓存 prompt_token_ids 的 np.int32，并在 add_request 里用 np.copyto 写入 token_ids_cpu，避免长 prompt 场景反复 list->NumPy 转换开销（尤其是抢占/反复进出 batch 时）

set VLLM_USE_PIECEWISE=0

新增环境变量 VLLM_USE_MARLIN_W16A16_MOE，用于显式启用 Marlin W16A16 MoE experts
在 fused_moe 中当开关开启且实现可用时，调用 fused_experts_impl_w16a16_marlin
增加 Marlin W16A16 MoE 实现与 reduce 路径

add VLLM_USE_OPT_RESHAPE_AND_CACHE、VLLM_USE_FUSE_SILU_AND_MUL and VLLM_USE_TOPK_RENORM for qwen3-30b

update VLLM_USE_PD_SPLIT=0 (for dspk)and  VLLM_USE_PD_SPLIT=1 (for others)

add VLLM_USE_PP_SYNC to use pp sync
update qwen3 of rmsnorm

set default_max_num_batched_tokens = 10240
update qwen3_moe of layernorm
off lightop of moe_fused_gate

add VLLM_USE_PD_SPLIT to split prefill and decode
replace triton_ of rms and act_and_mul
