added GitHub star CTA with direct update nav links

[jayanthi1406]

hi @vasanth642 this PR introduces a “Star on GitHub” call-to-action to encourage users to support the project.

Changes Made

• Added a CTA button in the history panel for starring the repository
• Implemented direct redirection to the official CubeIt GitHub page
• Updated navigation menu links to point to the correct repository
• Ensured consistency with existing UI and responsiveness across devices

Improvement

As suggested, instead of creating a separate page, users are redirected directly to GitHub when interacting with the CTA. This reduces friction and improves user engagement.

Notes

• The CTA is placed in the history panel for better visibility
• Styled to match the current design system

Hi @jayanthi1406 , the seperate CTA button in the history panel is not required.
The actual expected change is that there is already a "star on github" option in the sidebar and when the user clicks that option it will redirect them to the official CubeIt Github page where they can star the repository .

here is the option highlighted in the image.
Kindly do the following changes .
