C3D-0133 · READ-ONLY: find the IPF-to-CL dimensions [DIM-READ] done

The IPF-to-centerline annotations are dimensions, not text, so an earlier text scan missed them. Dumps every Dimension in model space with its type, layer, style, measurement, text position and the two extension-line points it measures between, plus the available dimension styles. No changes.

C# payload

// READ-ONLY. The user's IPF-to-centerline annotations read "26.29" and are DIMENSIONS, not text -
// which is why the MText/DBText/Leader scan found nothing. Dump every Dimension in model space
// with its concrete type, layer, style, measurement and the two points it measures between.
// Nothing is modified.
