Modeling Data - BRepGraph iterators, ref caching, mutation APIs, and layer events (#1190)
- Add RelatedIterator, CacheKindIterator, LayerIterator, RefTransientCache - Add Builder::AppendFull, BuilderView::RemoveRef with orphan pruning - Add SetCoEdgePCurve, ClearFaceMesh, ClearEdgePolygon3D, ValidateMutationBoundary - Rename CoEdgeDef::Sense to Orientation, FreeChildRefIds to AuxChildRefIds - Propagate ref-modification events through LayerRegistry (deferred/immediate) - Extend DefsIterator/RefsIterator with filtered-kind iteration - Add CreateAutoProduct option to BRepGraphInc_Populate::Options - Update BRepGraph and BRepGraphInc READMEs
