PhysicsDataCache gains a `CellGraph` property (UCG Stage 1). The env-cell hook is placed at the very top of CacheCellStruct — before the idempotency guard and the null-PhysicsBSP early-return — so BSP-less cells are included in the graph even though they are dropped from the legacy _cellStruct map. PhysicsEngine.AddLandblock/RemoveLandblock mirror terrain registration into the graph via a null-guarded DataCache?.CellGraph call. Zero behavior change: CellGraph has no readers this stage. A using-alias (UcgEnvCell / UcgCellGraph) resolves the EnvCell name collision between AcDream.Core.World.Cells and DatReaderWriter.DBObjs.
