When a user records a taught skill on one Team Computer bot, manual
takeover on another bot in the same space cleared the teaching lease
without stopping the session. Teaching input then failed silently and
skills/stop could not release the replacement takeover lease.
Reject computer/takeover while another bot on the same computer is
recording, matching the existing Stop teaching first messaging guard.
