Issues

• Every non-final stamp of an SDF relief/incise stroke is bounded 4×strength wide, so a 4-sample stroke dirties 53× the bricks of one stamp

• C ABI: a multires gesture cannot enter a host undo stack; expose MultiresDelta / SculptLayerDelta as a clay_multires_delta record

• C ABI: export StrokeTransaction as an incremental stroke session (begin/append/end) so live-input hosts stop re-segmenting strokes
