Khalim Conn-Kowlessar 9f6f7608b9 slice 15b: +18 features — heating type code, hot water, windows, flat, supply ... Heating: primary_sap_main_heating_code (the SAP10 heating-system enum was the single biggest missing input), primary_emitter_temperature, primary_main_heating_fraction. Hot water: immersion_heating_type, shower_outlet_count. Windows: window_pct_living, window_pct_external, window_pct_permanent_shutters (area-weighted shares parallel to existing window aggregates). Dwelling: conservatory_type, has_heated_separate_conservatory. Flat-only block (sap_flat_details): flat_level, flat_top_storey, flat_storey_count, flat_location, flat_heat_loss_corridor (int sentinels like '20+' coerce to None for the categorical features). Energy supply: meter_type, pv_connection, wind_turbines_terrain_type. Also plumbs `air_tightness` EnergyElement, `sap_flat_details` and `has_heated_separate_conservatory` through the 21.0.1 mapper path (they were silently None before).
