Security improvements: Enable branch protection and add SECURITY.md

Security Improvements Needed

Hey there! I noticed a couple of security gaps in the repo:

1. No branch protection on 'master'

   • OSSF Scorecard flagged this as a warning
   • Leaves the main branch vulnerable to unwanted changes

2. Missing SECURITY.md file

   • No clear guidance on handling security issues
   • Makes it tough for people to report vulnerabilities properly

Suggestions:

• Enable branch protection for 'master' (PR reviews, status checks, etc.)
• Add a SECURITY.md with basics like:
  • How to report issues
  • Response timeframes
  • Supported versions

Happy to provide more details if needed.

Thanks for considering!
