New per-landblock data model for WB-style per-building cell scoping:
Building — BuildingId, EnvCellIds, ExitPortalPolygons,
occlusion-query state (Step 5 lifecycle)
BuildingRegistry — two-way indexed (by cellId + by buildingId);
single source of truth per landblock
BuildingLoader — static factory from LandBlockInfo.Buildings;
walks interior portals to expand cell sets;
collects exit portal polygons in world space
10 new unit tests cover data invariants + registry indexing + loader
mapping per the algorithm resolved in RR2 findings.
LoadedCell.BuildingId stamping wired in RR4. Render-time consumption
arrives in RR7 (Steps 1-4) + RR9 (Step 5) + RR11 (RenderOutsideIn).
