PR Summary

• Simplification of Message Structure
  The code in OpenAiSolution.php has been updated to make the structure of messages more straightforward. We have removed complex nested organization for user and system roles, making it easier to understand and work with. However, prompts for both user and system roles remain the same, ensuring clear communication.

• Enhancement of User Authentication Process
  In LoginController.php, we've enhanced the user login process by adding an authentication step after confirming user credentials. This included loading services from Illuminate\Support\Facades\Auth and introducing the code Auth::login($user); for authenticating the user. This ensures a more secure login procedure.
