feat(export): Add STL export with parameter dialog (v0.6.0)
- StlExportService: binary/ASCII STL writer (degenerate triangle
filtering, per-triangle normals) + B-rep re-tessellation
- StlExportDialog + StlExportViewModel: scope (merged/per-file),
format, unit scale (mm/inch/custom), mesh quality (current/fine),
live triangle count + size estimate; confirm before export
- Background export with UI-thread mesh snapshot (GeometryModel3D is
DispatcherObject; only frozen MeshGeometry3D crosses threads)
- Fine quality = 0.15x import precision: CADability GetTriangulation
returns cached mesh for coarser requests (no coarse option) and
triangle count is non-monotonic in precision (0.4x < 1x)
- SmokeTest --stl-export-test: binary round-trip incl. inch scaling,
ASCII structure, degenerate filtering, real-file fine re-tessellation
- Bump version to 0.6.0; update ARCHITECTURE/CLAUDE docs (Phase 15)
