feat(locker): wire get_locked_repository via LockArrayRepository

Implement LockArrayRepository::new/add_package and
CanonicalPackagesTrait::get_packages (delegating to inner
ArrayRepository), expose add_package on LockArrayRepositoryHandle, and
add set_root_package_alias on CompleteAliasPackageHandle.

With these in place, Locker::get_locked_repository is fully wired:
load each locked package, register it (plus its aliasOf for
AliasPackages) in package_by_name, then build CompleteAliasPackage
handles for lock-file aliases via as_complete_package() narrowing.

Drop the unused RepositoryInterface::clone_box default and the stale
inherent LockArrayRepository::clone_box (no callers).
