feat(celestial-ring): render the full-globe ring from a store

The celestial ring presents its overlay to a store and the scene chrome
renders it in the globe container, handing back the two canvases the
ring paints. The application shell passes the store in so the keyhole
helpers other packages import stay free of Vue. Without its canvases the
ring still tracks whether the globe is framed and turns itself off.
