Add GitHub Profile Analyzer with Advanced Stats and Comparison

Implement a new "GitHub Profile Analyzer" dashboard in the ReactVerse project with the following functionalities:

- Search and analyze any GitHub user profile using the GitHub GraphQL API.
- Display profile details, repositories, stats, recent activity, and contribution calendar.
- Compare two GitHub profiles side-by-side.
- Modern, responsive UI with advanced charts and stats.
- Home page card for easy access.
- Documentation updates in [README.md](https://github.com/commitra/react-verse/blob/main/README.md) and [CONTRIBUTING.md](https://github.com/commitra/react-verse/blob/main/CONTRIBUTING.md).
