Function abortedToolOutput

* Output for an aborted tool call. When the abort carries a user-cancellation * reason (the user pressed stop), say so explicitly so the model treats it as a * deliberate interruption instead of a system fault to theorise about or retry. * Any other abort keeps the neutral wording.
