/**
 * daemon/daemon-control.ts — `aibroker stop` / `aibroker restart` without lsof.
 *
 * Order, most cooperative first:
 *   1. an installed AND active service (systemd user unit / launchd agent) is
 *      driven through its own manager — killing the process behind its back
 *      would only make the manager start it again;
 *   2. otherwise ask the daemon to shut itself down over IPC (`shutdown`);
 *   3. otherwise signal the pid in ~/.aibroker/daemon.pid, written at start.
 *
 * Everything the steps touch is injected so the order is testable without a
 * daemon, systemctl or launchctl.
