fix(cli): stand up the cli primitive from the service

core.New no longer auto-registers the cli primitive, so cli.Register now registers it (via core.CliRegister) — registering the cli service IS a working CLI, driven by Core.Run() with no cli.Main wiring. cli.Init opts the primitive in via core.WithCli() so the cli.Main path keeps working.
