Adds boundary/outline/sharp/crease/flush classification of HLR projection edges in SvgSerializer, so CSS can style silhouettes, ridges, and valleys differently instead of drawing every edge identically (fixes the "ugly faceted sphere" problem from #3668). Classification happens pre-HLR on the original solid's real face topology (three prior attempts tried to classify HLR's own output, which carries no face topology at all and can't be correlated back by edge identity). Each class's visible portion is then extracted via HLRBRep_HLRToShape::VCompound(S)/OutLineVCompound(S), the same per-shape filtering mechanism already used for per-product segmentation, applied per class instead. Classes are tagged directly on individual <path> elements so Bonsai's merge_linework_and_add_metadata group-level class rewrite in operator.py never touches them. New settings: svg-ridge-angle-min-degrees, svg-valley-angle-min-degrees, svg-emit-flush-edges (ConversionSettings.h), wired through Bonsai's CreateDrawing operator and exposed via its redo panel.
