/**
 * DialogManager - handles modal dialogs (save, restore, startup).
 *
 * Per ADR-170, dialogs are native HTML <dialog> elements. Visibility
 * is controlled by `showModal()` / `close()`; ESC and backdrop-click
 * are handled by the browser. The manager attaches a `close` event
 * listener on each dialog so that any close (button, ESC, backdrop)
 * resolves the pending promise consistently. Buttons set the dialog's
 * `returnValue` before closing to communicate intent.
