Add CODE_OF_CONDUCT.md to improve community collaboration

[ananyasinha-1]

The repository does not currently include a CODE_OF_CONDUCT.md file. Adding one would help define clear community behavior standards and encourage respectful interactions among contributors. This would create a more inclusive and positive open-source environment for the project. I’d be happy to contribute this improvement.

Thanks for opening this issue! You can work on this.

Please use a standard open source code of conduct template (such as Contributor Covenant) and adapt it for the project where necessary.
