Swap/Warp to recent window in the same space

Yabai is an awesome tool and makes my mac much less painful. Thanks for writing this.

Currently, I've this mapping to warp to most recent window
```
alt - return : yabai -m window --swap recent; \
yabai -m window --focus recent
```

Although, when I switch to another space, come back to original space and hit this hotkey, it warps to a window in the space I switched from. Is there a way to restrict the `recent` to the space I am in ?

Start by tracing the `yabai -m window --swap recent` and `yabai -m window --focus recent` entry points and how they select the recent window. Check how the current space is identified, then verify that both operations select only a window in that space while preserving the existing recent behavior.
