Partition source-owned physical samples on the reference geometry.

Records expose point, weight, source_entity_id, representative_qpoint and section_qpoint. Weights are physical integration weights. The representative support sums the selected section weights at each quadrature point; lifted assembly retains each original physical weight. Missing samples contribute only to outside. Rebuild after changing the mesh or the sample geometry.
