navigate: answer a page's Leave-site prompt instead of hanging

A page with a beforeunload handler shows 'Leave site?' when the extension
navigates away. Nothing answered it, so chrome_navigate waited out its timeout
and the agent never learned why. The worker now hears Page.javascriptDialogOpening
and dismisses the dialog (stay/cancel); page.navigate fails at once and says so.
leaveIfAsked: true, for that call only, accepts a beforeunload prompt. Tool
description and primer tell agents when to use it and to ask the user when unsure.
