qing 9179281420 fix(pybot×actpred): v3 审计 P2 清零——验收链 fixed_range + 导出断言 + overrun 节流
- v3-P2-1: _npu_test/_onnx_validate 按 normalize_mode 分支(fixed_range 免 stats,
  HailoPredictor 透传模式,torch 参考同口径反归一化)
- v3-P2-2: export_deploy/export_onnx 一致性 diff 超 1e-4 即 sys.exit(P2-f 闭环)
- v3-P2-3: run_loop overrun 告警节流(第1次+每100次),降 hz 建议仅 >10% 输出
- P2-a1: default_column_weights 扩展列(action_dim>18)默认 1.0
- P2-c: 补 predictor 异常清理路径测试(异常传播 + finally 落盘)
- P2-d/P2-e: Resize 口径与 resume scheduler T_max 语义文档化
- R2-4: _set.sh 安装后断言 CPU 版 torch,误装 CUDA 即拦截
测试: pybot 89 passed (+1)、actpred 148 passed/18 skipped
