OpenCV 5 Released with New DNN Engine and Native LLM Support

OpenCV 5 发布：升级全新 DNN 引擎、原生支持大模型

OpenCV 5 introduces a graph-based DNN engine, raising ONNX operator coverage from under 23% in 4.x to over 80%, with native support for Transformer, VLM, and LLM workloads.

Why it matters: HKR-H/K/R all pass for a substantive OpenCV major release: graph DNN engine, ONNX coverage jump, and native Transformer/VLM/LLM support. Strong featured item, but below must-write model-lab release territory.
