    # Broadcast to every Driver constructed on the current
    # thread. Background threads (`MessageBus::TimerThread`,
    # etc.) sleep too, but their Drivers — if any — were
    # registered under a different thread, so they skip; the
    # filter is load-bearing because rusty_racer / quickjs.rb
    # VMs aren't thread-safe. Idle Drivers no-op
    # (`tick_real_time` short-circuits when `@timers_active`
    # is false), so the broadcast is cheap.
