feat(plugin): generate proxy stubs for the package and repository graph

Emit the eleven stubs a subscriber plugin's object-graph calls reach
(BasePackage through RootPackage, the installed-repository hierarchy,
RepositoryManager, InstallationManager). The generator learns the member
kinds these classes need: builtin interfaces contribute no closure entries,
public static properties are materialized, public instance properties
forward through __get/__set, __toString forwards like a plain method,
__clone throws (proxy clone semantics are still an open design question),
and a subclass stub may add interfaces to its inherited surface.
