Khalim Conn-Kowlessar fca8815991 slice 16c: envelope_heat_loss_w_per_k feature 
New module domain.ml.envelope sums Sigma(U*A) + y*A_exposed across every
sap_building_part on a cert. U-values come from rdsap_uvalues' cascade
defaults, so the feature is never null.

Per-part inputs: wall / roof / floor / party-wall / windows / doors.
Windows + doors are apportioned to the main part (first in the list)
per RdSAP10 convention.

Wired into EpcMlTransform.to_row; transform VERSION 0.1.0 -> 0.2.0
(MINOR bump for an additive column per the ADR-0007 policy).

7 envelope unit tests + 2 transform-level tests, all AAA. Reference
geometry: 100 m^2 age-G mid-terrace -> ~208 W/K; doubles for two
storeys; drops with better insulation; sums across extensions.

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.
