 * @example
 * ```typescript
 * @Middleware()
 * export class LoggingMiddleware implements MiddlewareInterface {
 *   async use(context: ExecutionContext, next: () => Promise<unknown>) {
 *     console.log('Before:', context.toolName);
 *     const result = await next();
 *     console.log('After:', context.toolName);
 *     return result;
 *   }
 * }
 * ```
