Khalim Conn-Kowlessar af51be1780 Slice 24: rooflight line (27a) for 000516 — SapRoofWindow datatype + cascade ... Closes 000516's §3 LINE_33 0.8215 W/K rooflight gap. Adds SapRoofWindow to EpcPropertyData (area + raw U from RdSAP10 Table 24 "Roof window" column, p.50/113) and iterates them in heat_transmission_from_cert alongside vertical windows — same SAP10.2 §3.2 curtain transform R=0.04. Rooflight area is subtracted from the main part's roof gross so net (30) + (27a) = original gross, leaving (31) area aggregate invariant. 000516 LINE_33 residual: 0.8215 W/K → 0.0038 W/K. Remaining 0.0038 is the same pre-existing wall-perimeter + per-window curtain precision drift biting 000474/477/480/490 (slice 27).
