I'd like to fix the issue about nushell integration in Linux

[PRIHLOP]

What do you want to change?

I'd like to fix the issue about shell-integration = nushell in Linux described in the issue #12378

Why do you want to make this change?

This bug affects users with enabled shell integration of nushell.
When user wants to open vim in new window by command ghostty +new-window -e vim with enabled nushell integration the expected action fails.
My main motivation is speed up the 1.3.2 milestone to complete and get a new release(1.3.2) with fix for annoying scroll bug for Linux :)

FYI, we're skipping 1.3.2 and going straight to 1.4.
