Adds PortalInfo struct and extends CellPhysics with CellBSP (third BSP for point-in-cell tests, typed CellBSPTree from DatReaderWriter), Portals (from envCell.CellPortals), PortalPolygons (resolved cellStruct.Polygons — portals reference visible polys, not PhysicsPolygons), and VisibleCellIds (populated for future use; envCell.VisibleCells is List<UInt16>, not Dictionary). Deletes CellPhysics.LocalAabbMin/Max and PhysicsDataCache.TryFindContainingCell — Phase D's AABB shortcut is gone. CacheCellStruct's AABB compute removed; the [cell-cache] diagnostic updated with portal/visible counts instead. CacheCellStruct signature gains an EnvCell parameter (one call site in GameWindow.cs:5384 updated). ResolveOutdoorCellId drops the TryFindContainingCell call; portal-graph CellTransit replaces it next. ResolveOutdoorCellIdTests object initializers had the deleted AABB properties stripped temporarily so the build stays green; the file gets replaced wholesale in the next commit (CellTransit integration). Those 2 AABB-containment tests continue to fail (they were pre-broken on this branch); no new failures introduced.
