Add CONTRIBUTING Guidelines

This repository does not currently have a CONTRIBUTING.md file.
To help new contributors understand how to get started and contribute effectively, we should add one.

Tasks

• Create a new file named CONTRIBUTING.md in the root directory.
• Include information such as:
  • How to fork and clone the repository
  • Branch naming conventions
  • How to submit pull requests
  • Coding style or formatting rules (if any)
  • Issue and PR guidelines

Why This is Important

• Helps new contributors understand the contribution workflow.
• Ensures consistency in how contributions are made.
• Reduces confusion and repetitive questions.
• Makes the project more contributor-friendly, especially during Hacktoberfest.
