Add a GitHub star message and repository link to the DemoWeb About page

[armanist]

Summary

Add a short message to the DemoWeb About page inviting users to star the Quantum repository on GitHub.

The message should include the direct repository link and live alongside the existing framework/about information.

Why

The DemoWeb About page is one of the built-in places where users see framework information such as:

• current version
• available CLI commands

That makes it a reasonable place to include a lightweight call to action asking users to support the framework by starring the repository on GitHub.

Goal

Add a concise star message and repository link to the DemoWeb About page template.

Proposed Direction

Update the DemoWeb About page so it includes a short message such as:

• Would you like to show some love by starring Quantum on GitHub?

along with a direct link to:

• https://github.com/softberg/quantum-php-core

The exact placement and wording can be refined during implementation, but it should fit naturally into the current About page layout.

Acceptance Criteria

• the DemoWeb About page shows a short GitHub star message
• the message includes the direct repository link
• the message fits cleanly into the existing About page layout
• the change is implemented in the shipped DemoWeb template so newly generated modules include it
