Fix project URL in documentation and update gitignore format

- Updated README.md to correct GitHub repository URL from github.com/FutureOSS/futureoss to github.com/Starlight-apk/FutureOSS
- Revised .gitignore file to use standard gitignore format instead of code block wrapper
- Corrected license badge in README from MIT to Apache-2.0 to match actual project license
- Fixed contribution guide URLs to point to correct repository location
