Escape should close run panel

While esc will close the suggestions panel, the same does not apply to the run panel. To be as fair as possible to control, we should make it smooth to quit, and to run the code.

Suggestion: esc to close the run pane

While others might disagree, I am hesitant about binding the rejection of suggestions with closing the output panel. To me they are two different kinds of interactions. E.g., closing the exploration panel of GitHub Copilot wouldn't close your console pane in the bottom.
