- profile.py: DP_FLAG 追加到 LAUNCH_ARGS 与 BOOTSTRAP（BOOTSTRAP 的 ${LAUNCH_ARGS}
引用在 env 解析阶段已内联，必须直接 append 到 BOOTSTRAP 末尾），并改为用
rendered 作模板展开源；修复 910c TP4/DP4 启动退化为 TP4 单 DP 布局导致
专家权重不分片 OOM(61.3GB/die) 的问题（顺带修复 p800/pro6000 同类隐患）
- cli.py/runner.py: bench 的 API model 名改用 SERVED_MODEL_NAME（vLLM 严格校验），
tokenizer 独立用 MODEL_PATH 路径并 --tokenizer 透传、docker client 挂载；
修复 910c/vLLM 场景 404 Not Found
- dsv4 910c profile 恢复标准加载参数(prefetch+multithread)；config.env per-TP
max-model-len 默认改为已验证值(32768/65536/131072)
- 实测: 910c TP4/DP4 16-worker 布局启动健康, sskj.bench smoke 40/40
