Published COCO test-dev AP without test-time augmentation: 37.4.

Modifications

The data-parallel module. prefix was removed and LibreYOLO v1 checkpoint metadata was added. Learned tensors are unchanged. The native graph strictly loads the official state dict and its hm, wh, and reg outputs are bit-exact against the pinned implementation. LibreYOLO replaces the legacy DCNv2 extension with torchvision deformable convolution.
