When sending to a destination whose identity isn't cached (e.g., peer hasn't
announced since app start), automatically call RNS.Transport.request_path()
and wait up to 5 seconds for the network to respond with the path.
This enables sending messages to known peers without waiting for their
periodic announces, improving UX for users resuming conversations.
