When curt_dnn_model is set, run the ONNX DNN per-pixel inference over
curt_save_select across all available scenes (not just the first few),
saving -DNN-RECT / -DNN-HYPER-RECT. Slice labels carry timestamp + absolute
frame index for matching to real targets. New curt_dnn_thresh (6 sites in
IntersceneMatchParameters) zeroes the (Vx,Vy,s) field below confidence s -
display/FP-suppression only. inferROI tiles the ROI batch (CHUNK) to bound
ONNX Runtime activation memory.
