macOS: tabs respawn by themselves when closed via "exit"

[Cooksauce]

Details:

• This refers to behavior configured by: quit-after-last-window-closed = true
• I've hit this off-and-on for a bit... but still not sure exactly how to reproduce it

Rough Sequence of Events:

1. ghostty is completely closed
2. open ghostty
3. in tab[0] --> ls (run some command)
4. in tab[0] --> cmd+t --> new tab opens
5. in tab[1] --> ls
6. in tab[1] --> run: exit --> tab[1] closes
7. in tab[0] --> run: exit --> tab[0] closes --> ghostty closes (as configured)
8. open ghostty --> tab[0] and tab[1] respawn (unexpected behavior)
   • the tabs are opened back to the (non-default) directory they were in when closed
   • at this point, repeating steps 6 thru 8 continue to result in respawns
9. in tab[1] --> quit ghostty via traditional cmd+q
10. open ghostty --> opens as expected with a single tab

Feels like it could be related to #2273

This is related to window-save-state. We unfortunately don't have control over when macOS decides to save window state and sometimes previously closed windows return. We haven't figured out a way to make this perfect. For now, you can set window-save-state = never to fix this.
