Khalim Conn-Kowlessar 244f4555ac slice 20a.1: route ventilation through predicted_space_heating_kwh (v2.7.1)
v20a added ventilation_heat_loss_w_per_k as a standalone feature but never
connected it to the HLC inside predicted_space_heating_kwh, so the
downstream physics aggregates (predicted_ecf, predicted_total_fuel_cost,
predicted_log10_ecf — the top-10 model features) never saw the
infiltration signal. Importance for ventilation_heat_loss_w_per_k was rank
58/196 (importance 30) vs envelope's rank 21 (86).

Adds the ventilation column to the envelope-conduction HLC before
applying HDH and efficiency, so chimney + draught-proofing signals flow
through the physics aggregates the model actually uses. Default 0 keeps
backwards compatibility.

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.
