autoreload desk on save.

Hello
Thanks for desk it's really clever and useful
I think it will be nice to add a trigger when we edit a desk from inside (`desk edit`) to exit and reload the desk.

Great script!

Start at the `desk edit` entry point and trace how editing a desk currently exits or returns to the workspace. Implement the requested save trigger so the desk exits and reloads after an edit, then verify the behavior manually from `desk edit`.
