refactor(streaming): complete landblock presentation cutover

Browse source 
Remove the legacy GameWindow apply path and make the concrete render, physics, and static publishers the only production owner graph. Serialize full-window retirement with shared-origin teleport and session boundaries so old coordinate-frame resources cannot survive into a new world or login.
