Khalim Conn-Kowlessar 706d1b5b66 slice 11a: PV array aggregates + capacity_source flag
Fifteen PV features land: has_pv (bool), pv_capacity_source (str
categorical: measured / estimated_from_roof_area / none),
pv_array_count, pv_total_peak_power_kw, eight peak-power-by-octant
columns (pv_peak_power_kw_{N..NW}), peak-power-weighted
pv_avg_pitch and pv_avg_overshading (nullable), and
pv_percent_roof_area (nullable — populated only on the estimated
branch).

Dispatches on the SAP10 EpcPropertyData.SapEnergySource shapes added
in slice 10.5: photovoltaic_arrays populates → measured;
photovoltaic_supply.none_or_no_details.percent_roof_area > 0 →
estimated; everything else → none. percent_roof_area == 0 is the
canonical no-PV payload and surfaces as 'none', not 'estimated'.

domna-domain

Shared domain types — Property, Properties, BaselinePerformance, Plan, PlanPhase, Scenario, ScenarioPhase, ScenarioSnapshot, Recommendation, OptimisedPackage, EpcPropertyData, etc.

Boundary: types only. No persistence, no IO, no business logic. Other packages and services depend on domna-domain; this package depends on nothing internal.

Domain definitions live in ../../CONTEXT.md. New types added here must match the glossary terms.
