Highlights

This release migrates OpenCvSharp to OpenCV 5 (native + managed) and targets .NET 8+ only. Highlights:

• OpenCV 5 port: native OpenCvSharpExtern rebuilt against OpenCV 5.0.0, with module relocations (features2d→features, calib3d split, new ptcloud wrapper) and behavior-change fixes.
• New high-level DNN APIs: Model (Classification/Detection/Segmentation/Keypoints), text recognition/detection, Tokenizer, TFLite reader, and richer Net introspection/tracing/profiling.
• New feature & geometry wrappers: ALIKED, DISK, LightGlue, ANNIndex, AffineFeature, USAC polishing, multi-view camera calibration, ptcloud mesh I/O, TrueType text rendering (FontFace), typed Mat<T>/SparseMat<T>.
• Large internal modernization: SafeHandle + LibraryImport P/Invoke throughout, allocation-free InputArray/OutputArray ref structs, lazy/leak-free Mat arithmetic via a managed MatExpr tree, UTF-8 path/string handling, and removal of several legacy helper types.
• Infra: macOS x64/arm64 CI restored, Docker packaging cleanup, test project moved off SixLabors.ImageSharp to SkiaSharp/LibTiff.NET, various dependency bumps.
