PR Summary

• Introduction of a New Route
  There is a new route added, labeled as '/dev', specified in the file titled 'config/routes.php'. This new route leads to a destination referred to as the 'DevServerController' class.

• Creation of a Stream Endpoint through New File
  A brand new file, 'DevServerController.php', has been placed in the 'src/Controller' folder. This file's purpose is to create a continuous stream of data, meant for server-sent events. This is done through incorporating a couple of resources: 'DataResponseFactoryInterface' and 'Aliases'. The new function, dubbed the stream method, establishes such a server-sent events stream, sets up necessary data exchange headers, and returns a response containing the created stream in the body part of the response message.
