- hailo_infer: 帧输入按 input_layerN 排序绑定（vstream 报告顺序实测 为 1,5,4,3,2，按报告顺序会 frame1/frame2 错位），新增 --pred-token - gen_calibration: pred_token 校准改为学习值 ±30% 抖动，修复常量 校准量化退化（scale=18571.7，任何输入都被量化成 0） - export_deploy: 新增 --pred-token-out 保存学习值供推理端喂入 - dfc_compile: parser/optimize 后自动检查输入层连通性，断开即报错 - 新增 _npu_test.py（NPU 4 角敏感性复验）与 _onnx_validate.py （编译前 ONNX 数值门槛），test_actpred 补乱序帧序用例
