Functions
QVector< int >	mesh::reorderTrianglesFirst (MeshResult &mesh)
	Reorder cells triangles-first, stable within each class. Returns the old→new cell index map. Shared with meshquadmatch.

QuadCleanupStats	mesh::cleanupAndSmoothQuads (MeshResult &mesh, const QSet< int > &movable, const QuadCleanupOptions &opts, QVector< int > *vertexOldToNew)
	Run cleanup then smoothing. `vertexOldToNew` (optional) receives the vertex remap after doublet compaction (-1 = removed); identity when nothing was removed. Cells are rebuilt triangles-first afterwards.

Topological cleanup and guarded smoothing inside quad regions (QUAD_MESHING_REDESIGN_PLAN §4.4g–h): doublet removal, valence-driven diagonal swaps, then Jacobi "parallelogram" smoothing accepted only when the minimum scaled Jacobian around the vertex does not drop and every incident cell keeps its orientation (quads: convexity). Only vertices in the movable set are moved or removed.
