Make Wezterm behave like Ghostty's Quick Terminal, i.e. use a keybind to focus/hide a scratch terminal that always stays on top.
Keybind: Alt-`
- First press: Spawns a wezterm terminal with workspace
"_scratch"and focuses it in the middle of the screen. - Subsequent pressees: Hides the terminal if it is focused. Otherwise bring the terminal to the centre and focus.
