// CHEAP + idempotent: it first checks `oxmgr service status` and SKIPS the
// install when the service is already registered. This matters a lot —
// re-running `oxmgr service install` re-bootstraps the launchd/systemd job,
// which restarts the oxmgr daemon itself, and a daemon restart kills and
// relaunches EVERY managed process (not just ours). Doing that on every
// `ay serve install` / `ay schedule` was bouncing unrelated daemons — e.g. a
// VS Code `serve-web` server running under another managed process, which took
// the user's editor (and any agent running inside it) down with it.
//
// Best-effort: returns false on any failure (e.g. a system-level systemd unit
// that needs sudo) without aborting the caller — the process is still managed,
// just not boot-persistent.
