refactor(cli): ♻️ separate UI logic into dedicated module

[YagoBorba]

📋 Description

This PR executes a significant architectural refactoring of the CLI commands. It separates the business logic and orchestration from the UI logic (user prompts and console logging) by introducing a dedicated UI module located at packages/cli/src/ui.ts.

This change dramatically improves code quality, testability, and maintainability by adhering to the Single Responsibility Principle. Command files are now cleaner and focused on what to do, while the ui.ts module handles how to interact with the user.

📝 How Has This Been Tested?

• Unit tests pass: The entire existing test suite was run to ensure no regressions were introduced.
• Manual testing completed: Manually executed the primary flows of init, generate, git, release, and config to verify that the refactored UI prompts and logs behave identically to the previous implementation.
• CI/CD pipeline passes: The build and test jobs complete successfully.

📚 Additional Notes

This refactoring significantly improves the testability of the CLI commands. Future unit tests can now mock the ui.ts module as a whole, rather than mocking inquirer and console.log individually, leading to cleaner and more robust tests.
