IncomingMessage's docstring and the callbacks page said every server
notification reaches message_handler, but notifications/cancelled is
applied by the dispatcher and a subscription ack for a live listen()
stream is consumed by that stream, so neither is delivered. Say so.
Also drop the "shared type aliases" mention from the interaction
suite's layout guide now that _helpers.py holds only the recording
transport.
