wuyongtao ec7d8c0a3d fix: 算力节点任务/GPU 统计纳入评测与推理占用,补充测试依赖
- compute_nodes() 的 current_running_jobs 纳入运行中的评测任务(eval_tasks)
  与已加载的推理模型(compare_tasks 持久化状态 + 内存标记兜底),
  多节点时 GPU 被评测/推理占用不再显示 0/1
- gpus() 直接按 eval_tasks / compare_tasks 派生 GPU busy/reserved 状态,
  修复 gpu_id=0 时 or -1 导致匹配失败;删除评测后 GPU 不再残留 busy
- 评测不再复用 mark_inference_loaded 内存标记,GPU 占用由任务数据驱动
- requirements.txt 补充 pytest / ruff(此前仅声明在 pyproject dev 可选依赖)
