Repository cleanup: README, CONTRIBUTING

We need to clean up and improve the overall structure and documentation of this repository to ensure consistency, clarity, and ease of use for contributors and users.

Tasks:

• Review and update README.md with clear purpose, setup instructions, and usage examples
• Create a CONTRIBUTING.md with contribution guidelines, coding standards, and pull request process
• Ensure presence of a LICENSE file and verify its accuracy
• Restructure the /documentation folder (if present) for better navigation and readability
• Ensure consistent formatting and naming across documentation files
• Check and update badges (build status, license, etc.) in README.md
• Archive or remove outdated or deprecated documentation files

Goal:

Improve onboarding, encourage contributions, and ensure high-quality project documentation.
