Documentation : Add Code Of Conduct File to project

### Suggestion: Add Code of Conduct

I suggest adding a **Code of Conduct** file to the project repository.

A Code of Conduct helps in:
- Defining standards for how to engage in a respectful and inclusive way.
- Setting clear expectations for behavior from all contributors.
- Making the community more welcoming and professional.

### Proposed Steps
1. Add a `CODE_OF_CONDUCT.md` file in the root of the repository.
2. Use a standard template (e.g., [Contributor Covenant](https://www.contributor-covenant.org/)) or customize it as per the project's needs.
3. Link to this file from the `README.md` so contributors can easily find it.

This will help establish a healthy and collaborative environment as the project grows.
