PR Summary

• Addition of a new PHP library to the project's dependencies
  Introducing a new library named "friendsofphp/proxy-manager-lts" version "^1.0" to the project, which is listed in the composer.json file. This library helps us manage proxy classes which can enhance the performance and memory usage of the application.

• Modification of route configuration in the app
  The route addition syntax in the router.php file was changed from ->addGroup( to ->addRoute(. This update results in more standardized route registration.

• Introduction of lazy loading for the VersionProvider class
  In the application.php file, we added lazy loading for the VersionProvider class. Lazy loading is a design pattern which defers the loading or initialization of resources until they are needed. In our case, the VersionProvider class will now only be loaded when it's actually needed, contributing to potential improvements in application performance.

• Addition of a 'lazy' flag to API responses
  In the InfoController.php file, we now include a new key-value pair in the API response: 'lazy' => $this->versionProvider instanceof \ProxyManager\Proxy\LazyLoadingInterface . This means the response will now tell us if the versionProvider property was loaded lazily.

• Updated Acceptance Test to check for the 'lazy' attribute
  In our tests, specifically the SiteCest.php file, we now check for the presence of 'lazy' => true in the response array from the API. This aids in verifying that the lazy-loading feature is working correctly.
