 * Asgardeo middleware that integrates authentication into your Next.js application.

 * @param handler - Optional handler function to customize middleware behavior
 * @param options - Configuration options for the middleware
 * @returns Next.js middleware function
 *
 * @example
 * ```typescript
 * // middleware.ts - Basic usage
 * import { asgardeoMiddleware } from '@asgardeo/nextjs';
 *
 * export default asgardeoMiddleware();
 * ```
 *
 * @example
 * ```typescript
 * // With route protection
 * import { asgardeoMiddleware, createRouteMatcher } from '@asgardeo/nextjs';
 *
 * const isProtectedRoute = createRouteMatcher(['/dashboard(.*)']);
 *
 * export default asgardeoMiddleware(async (asgardeo, req) => {
 *   if (isProtectedRoute(req)) {
 *     await asgardeo.protectRoute();

 * ```typescript
 * // Advanced usage with custom logic
 * import { asgardeoMiddleware, createRouteMatcher } from '@asgardeo/nextjs';
 *
 * const isProtectedRoute = createRouteMatcher(['/dashboard(.*)']);
 * const isAuthRoute = createRouteMatcher(['/sign-in', '/sign-up']);

 * export default asgardeoMiddleware(async (asgardeo, req) => {
