Tested on the aircraft. A second ARSDK handshake is accepted and telemetry is
redirected to it; the first session's frames stop while it still reports
connected = True. So the claim inherited from pyparrot's error text, which had
reached our error messages, tool descriptions, simulator behaviour and a test
name, was wrong in the most misleading direction: a refusal would be loud, and
this is silent.
The simulator now models the takeover by default; refusal stays available
because a client must handle a non-zero status anyway.
