public class AboutWindow
extends GenericDialog

Displays comprehensive information about the Gaia Sky application.

This window extends GenericDialog and uses a tabbed layout to organize content into Help, About, System, and Updates (when applicable). It provides access to external resources such as the project homepage, documentation, source repository, and social media channels.

Key features include:

• Displaying the current version, build number, and runtime environment.
• Listing credits and author contact information via Link components.
• Conditionally showing an Updates tab based on the launch method.
