fix(build): 消除COPY ./vllm_overrides — vendor_overrides预置到qwen3_6_scripts/

竞赛平台docker build失败，无日志。最大嫌疑：
  COPY ./vllm_overrides /workspace/vllm_overrides
26e6cb4(成功)只有3个COPY，HEAD多了这第4个COPY。

修复：把9个vllm_overrides文件直接放进qwen3_6_scripts/vendor_overrides/
Dockerfile回到3个COPY（和26e6cb4结构一致），去掉Step 4 staging。
patch_ops.sh不需要改——它已经从./vendor_overrides/读取。

COPY数量: 4→3 (匹配26e6cb4)
Dockerfile行数: 74→48 (更简洁)
Step数: 8→7 (去掉staging step)
