Add logprobs and top_logprobs to streaming and non-streaming responses. Use Triton to process requested logits rows directly and skip top-k selection when only the sampled token score is requested. Pack candidates by request and preserve alignment through MTP filtering.

/v1/chat/completions支持logprobs和top_logprobs,流式和非流式都能返回生成 token 的概率。开启logprobs后,可以选择返回每个位置的 0–20 个候选。K=0路径只统计排名。候选按各请求的实际K打包,再批量异步拷到 CPU。验证
main的5e9a7e66a后,在 H200 上重跑 API、GPU 采样、结构化输出、共享内存和 PD 回归,294 项全部通过。git diff --check通过。相关讨论 #1124。
