AetherDb ship-authoring centre prints Shape.CenterOfMass; Package asks it and moves Ship Root so that point sits
at the world origin, after regenerating the unowned map icon, shield and tractor from the render meshes (Keep
leaves one alone). Package never makes a hull collider (ruling package-frame-defer-collider). smoke_package's
bound-collection rollback cases now rebind to a different path so a rollback that restores keys but not values fails.
C# not yet built when committed; the Blender smokes and Python unit tests pass.
