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

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

Notes

Relevant code:

• src/Module/Templates/DemoWeb/src/Views/pages/about.php.tpl
• src/Module/Templates/DemoWeb/src/Controllers/PageController.php.tpl

Start with src/Module/Templates/DemoWeb/src/Views/pages/about.php.tpl and review the existing About page layout and framework information. Add the concise GitHub star message and direct repository link there, then confirm the shipped template will include it in newly generated modules and that the layout remains clean.
