What
Opening a job from the fleet view now checks whether another terminal already holds that session and shows "Can't open — this session is running in another terminal" instead of attaching. No flag guards it.
Details
The roster of live sessions is consulted before attaching; a holder means the open is refused outright rather than respawning.
The same message was already used by the peer-backend path; it now covers the local path too.
Evidence
Can't open \u2014 this session is running in another terminal
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
