Add YouTube demo video and live website links to README

[Copilot]

Adds prominent links to the project's YouTube demo video and live website deployment to improve discoverability and user engagement.

Changes

Added a new "🚀 Live Demo & Video" section to the README.md with:

• YouTube Demo Video: https://youtu.be/pwKp3CORFaM
• Live Website: https://mind-mate-sepia.vercel.app/

The section is strategically placed after the technology badges and before the feature screenshots for maximum visibility.

Implementation Details

• Created styled badge buttons that match the existing design aesthetic
• Used shield.io badges with appropriate colors and icons (YouTube red with logo, website blue with globe emoji)
• Added descriptive text encouraging users to watch the demo and try the live application
• Maintained consistency with existing markdown structure and formatting

Benefits

• Increased Engagement: Users can immediately access the live demo and see the project in action
• Better User Experience: Clear call-to-action buttons guide users to try the application
• Professional Presentation: Badge-style links maintain the polished appearance of the README
• Improved Discoverability: Prominent placement ensures visitors don't miss these important resources

The additions provide users with instant access to experience MindMate through both video demonstration and live interaction, significantly improving the project's accessibility and user onboarding experience.
