/**
 * Creates and configures an Arkos application instance.
 *
 * Arkos extends Express with a small set of methods for registering routers,
 * loading route/service hooks, and booting the application. All Arkos-specific
 * setup (`app.build()`) must happen before the app starts
 * accepting requests.
 *
 * @example
 * ```ts
 * // Simple setup
 * import arkos from "arkos";
 *
 * const app = arkos();
 *
 * app.use(reportsRouter);
 *
 * app.listen();
 * ```
 *
 * @example
 * ```ts
 * // Custom HTTP server (e.g. for WebSockets)
 * import arkos from "arkos";
 * import http from "http";
 *
 * const app = arkos();
 *
 * app.use(reportsRouter);
 *
 * await app.build();
 *
 * const server = http.createServer(app);
 * app.listen(server)
 * ```
 *
 * @see {@link https://www.arkosjs.com/docs/core-concepts/routing/setup}
