ExecQueue.Shutdown does not wait for a function that is already executing, so Close could tear down magicConn, dns, wgdev, and tundev while a queued linkChange was still using them, panicking during shutdown. Add ExecQueue.ShutdownAndWait, which discards queued functions that have not started and waits for the in-flight one, and use it in Close with a bounded context before tearing anything down. The eventbus client is closed first and is the queue's only producer, so no new work can arrive after the drain.
