Orca-Cad: port SnapOrca Design (parametric CAD tab) onto mainline OrcaSlicer

Browse Source

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.
