Add `TransformClass` for describing how restrictive an `Affine` delta is, with public `Affine` helpers for classifying a transform relative to identity or another transform. Classify matching linear parts directly so translation-only differences avoid inversion, including singular transforms, while still using relative deltas to recognize rotation, reflection, and uniform-scale changes.
