🧪 Extract Version Logic and Improve Test Coverage

[hatimhtm]

🎯 What

The core isNewerVersion logic previously resided within AppDelegate.swift, coupling version comparison directly with the app delegate logic and making testing difficult. In addition, no test files existed for this code. This PR addresses these issues by extracting the logic into its own reusable VersionUtils.swift structural file and introducing a suite of test files.

📊 Coverage

1. VersionUtils: Extensive tests have been added in Click2MinimizeTests/VersionUtilsTests.swift testing the extracted logic against:

• Newer versions with varying digit lengths.
• Older versions with varying digit lengths.
• Identical versions.
• Edge cases such as differently sized versions (e.g., 1.0.0 vs 1.0).

2. AppDelegate: Tests have been introduced in Click2MinimizeTests/AppDelegateTests.swift verifying structural initializations in AppDelegate.swift, such as setupAppDict functionality and proper data assignment in DockItem.
3. Xcode Project Setup: Proper Xcode project testing targets and file inclusions (Click2MinimizeTests) have been successfully generated and incorporated.

✨ Result

Test coverage is substantially improved, and complex core logic is structurally isolated into testable components. As a result, regressions in version handling are less likely, code logic is decoupled from side-effect-heavy files like AppDelegate, and the codebase is easier to adapt and verify.
