docs(shared): bygg-energi mikro-eksempel — OKF-bundle + golden + load-bearing test

Persistent dev-fixture for energieffektivisering (energiledelse/M&V), valgt for
sin lærings-overflate: gapet mellom modellert besparelse (validatoren regner) og
faktisk realisert besparelse i drift (eksperten kjenner) — det ExpeL skal lære.

Ett kontorbygg, ett LED-retrofit-tiltak. OKF-bundle (index/project/hypothesis/
methodology/reference/verdict) bærer kontekst-laget; verdict-led-fro.md koder
realiseringsgraden (RR ≈ 0,82, forankret i National Grid SBS 2010) som ExpeL-frø.

Energi mappet inn i den EKSISTERENDE kost-IR-en uendret (affected = byggets totale
energikostnad, claimed = modellert besparelse ~10 % < 30 %-cap), så validatoren
kjører som-den-er — src/ urørt. golden.json fryser de seeded percentilene; testen
beviser at fixturen er konsumerbar (validerer, ikke Rejection), ikke bare til stede.

Domenetall verifisert mot primærkilder (EVO/IPMVP, DOE/NREL UMP, CPUC, fire
evalueringsstudier); norsk energipris mot SSB Q1 2026. README + shared/README
oppdatert (eksempel finnes, ikke lenger "planned"). Suite 121/4, ruff+mypy rene.
