Ship S2: the game composes and loads mod ships

Browse source 
Boot opens the derived catalog when GameData/Mods holds packages
(ShipModCatalog.ResolveCatalog), preloads each hull's GLB into an assembled
inactive prototype (ShipModShips), and LoadEntity clones it when the hull names
a Visual. ShipModPlan decides which anchor fills which ShipInstance slot; a
ShipModTemplate prefab carries the shared effects. Continue refuses a run that
names a design the catalog no longer holds (RunSave.RequireDesigns).
