Code refactoring

[DenTray]

Description

What needs to be done?

Refactor the existing init command code by moving all logic related to readme file generation into a new separate class called ReadmeGenerator. Implement the ReadmeGenerator class to handle all aspects of creating the readme file. Additionally, write unit tests to fully cover the functionality of the new ReadmeGenerator class.

Expected Outcome

What is the expected result?

The init command code is cleaner and more modular, delegating readme file creation to ReadmeGenerator. The new class is fully tested with unit tests, ensuring reliable readme file generation. Existing command behavior remains unchanged from the user's perspective.

Verification Scenarios

How can this be tested?

• Run the refactored init command and verify the readme file is generated as before.

• Run all unit tests for the ReadmeGenerator class and ensure full coverage.

• Confirm no regressions appear in the init command functionality.

• Check no debug information or errors appear in the console during execution.
