Adding Code of Conduct to establish community guidelines

[srimadhuri18]

Description

This repository currently does not include a Code of Conduct.

Adding a CODE_OF_CONDUCT.md helps set clear expectations for respectful and inclusive behavior, making the project more welcoming for contributors and users.

Many open-source projects adopt a standard Code of Conduct (such as the Contributor Covenant) to ensure a positive collaboration environment.

Expected Behavior

• Define acceptable and unacceptable behavior
• Provide guidance for reporting issues
• Promote an inclusive and respectful community

Proposed Solution

• Add a CODE_OF_CONDUCT.md file at the root of the repository
• Use a widely accepted template (e.g., Contributor Covenant)
• Customize contact/reporting details if required
