Bug Description

claude code running inside tmux wont see a running cursor instance when running /ide.
I also have tmux auto start in cursor terminals, and that does not recognize that it is running inside cursor

3. run claude
4. /ide Shows no available ides

Expected Behavior

Show running cursor. This works if I am not inside tmux
