The code has been tested on a clean Laravel project and everything works as expected.

[artengin]

The .env.example file is taken from a clean Laravel project, which is generated automatically during Laravel installation.

I installed Laravel using this command:

composer create-project --prefer-dist laravel/laravel laravel

Pull Request Overview

This PR adds functionality to automatically generate a .env.development file by copying from .env.example if the development environment file doesn't already exist. This ensures that the development environment configuration is always available during project initialization.

• Adds automatic creation of .env.development file from .env.example template
• Updates test mocks to include the new copy operation
• Maintains existing environment file update functionality
