Grafts the sketch-first CAD environment from snaporca-cad onto the mainline OrcaSlicer/OrcaSlicer base (vs snaporca's Snapmaker/OrcaSlicer base): - 133 new files: CadDocument/SketchEngine/GeometryEngine/SketchConstraints/ SketchSolver/SketchInference/ThreadStandards + vendored libslvs solver; DesignPanel/DesignCanvas/DesignSketchTool/SketchInlineEditor GUI; GLGizmo Primitive/Sketch; 75 design icons; Catch2 tests. - Integration hooks ported to mainline's diverged versions: Design tab in MainFrame, embedded design viewport + sketch overlay + per-canvas chrome suppression in GLCanvas3D/PartPlate, gizmo registration, Plater accessors, CMake wiring (libslvs subdir, CAD sources, OCCT ModelingAlgorithms=ON). Structural integration complete; build verification pending. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01BVzKmX6Y1aEteit1HTXG4Q
