/**
 * Updater event name constants.
 *
 * Use these instead of hard-coding string literals when subscribing to
 * updater events from JavaScript:
 *
 *     import { Events, Updater } from "@wailsio/runtime";
 *
 *     Events.On(Updater.Events.UpdateAvailable, (e) => {
 *         console.log("update found:", e.data.version);
 *     });
 *
 *     Events.On(Updater.Events.DownloadProgress, (e) => {
 *         const p = e.data;
 *         console.log(`${p.written} / ${p.total} bytes`);
 *     });
 *
 * Mirrors the Go-side constants in `pkg/updater/events.go` and the
 * user-action constants in `pkg/updater/window_lifecycle.go`. Any
 * changes here must stay in sync with those files — there's an
 * integration test that asserts the strings match.
