Add Code of Conduct

Summary

This PR adds a formal Code of Conduct to the project using the Contributor Covenant v2.0 standard, establishing clear community behavior standards and enforcement procedures.

Closes #96

Changes

Added

• CODE_OF_CONDUCT.md: Contributor Covenant Code of Conduct v2.0
  • Defines community standards and expected behavior
  • Includes enforcement guidelines with escalation ladder (Correction → Warning → Temporary Ban → Permanent Ban)
  • Provides reporting mechanisms via GitHub Issues and Security Advisories
  • Based on industry-standard Contributor Covenant template

Updated

• CONTRIBUTING.md: Updated Code of Conduct section
  • Replaced brief mention with reference to the new CODE_OF_CONDUCT.md file
  • Added reporting instructions for unacceptable behavior
  • Includes links to GitHub Issues and Security Advisories for reporting

Motivation

• No formal code of conduct existed for the community
• CONTRIBUTING.md only briefly mentioned "Be respectful and inclusive"
• New contributors lacked clear guidelines on expected behavior
• No enforcement procedures were documented for handling violations

Benefits

• ✅ Establishes clear community standards
• ✅ Provides enforcement procedures and escalation guidelines
• ✅ Improves contributor experience with transparent expectations
• ✅ Aligns with industry best practices (Contributor Covenant)
• ✅ GitHub will recognize and display the code of conduct badge

Testing

• Verified CODE_OF_CONDUCT.md follows Contributor Covenant v2.0 format
• Confirmed CONTRIBUTING.md properly references the new file
• Checked all links are valid and point to correct GitHub resources
