#### ⚠️ this pr targets #9977
## Summary of the Pull Request
This adds support for part of the `monitor` property for `globalSummon`. It also goes a little off-spec:
```json
"monitor": "any"|"toCurrent"|"toMouse"
```
* `monitor`: This controls the monitor that the window will be summoned from/to
- `"any"`: Summon the MRU window, regardless of which monitor it's currently on.
- `"toCurrent"`/omitted: (_default_): Summon the MRU window **TO** the monitor with the current **foreground** window.
- [**NEW**] `"toMouse"`: Summon the MRU window **TO** the monitor where the **mouse** cursor is.
When I was playing with this, It felt like `toMouse` was always what I wanted, not `toCurrent`. We can always just comment that out if we think that's contentious - I'm aware I didn't originally spec that.

## Detailed Description of the Pull Request / Additional comments
I made `toMouse` the default because it felt better. fite-me.jpg
