fix(cli): stand up Init's cli via Register, not core.WithCli()

core.WithCli() inside core/cli forces the default cli back in (the very thing removed from core.New) and double-registers when an app also adds the cli service. Init now stands up the cli the one consistent way — via the package's own Register service.
