Attach the tools, data and controls bound to one globe as scene parts

Each phase builds its session objects once (shell, layer manager and presentation, Director, annotation board, Draw, Import, voice, debug handle) and registers the parts bound to one globe: the shell's later attachments, Cockpit clouds, the catalog binding and sonar, the Director's scene, the Cesium or Navara tools and the debug handle's globe fields. A page with a scene host attaches them to every engine; a host that never switches attaches them once, as before. The shell releases its globe before the data layers detach, and the Navara notice goes with its engine.
