- Migrated `TopClass_FaceClassifier` / `TopClass_Classifier2d` implementations to `.pxx` and updated BRepClass/Geom2dHatch wrappers to use them (removing `_0.cxx` generator glue). - Updated BRep class helper headers to use header inlines instead of separate `.lxx` files, and added/rewired passive/face classifier implementations. - Extended `NCollection_DynamicArray` / `NCollection_KDTree` APIs (insert helpers, callback-based range query) and added GTests for the new vector insert operations.
