#Overview

Optimistic writes with an Undo toast.

run applies the local change at once, shows a toast with an Undo button, and either commits now (undo given) or when the window closes. It resolves once the change is visible and, in immediate mode, accepted.

Call it straight from the click, not from inside a useAction: the change must reach the screen in the click's own frame, and useAction awaits its react:action:begin listeners before the handler starts. run reports its own failures (rolled back, then react:action:error, which the root ActionErrorToaster shows). Ctrl+Z / Cmd+Z undoes the newest open toast.
