CodeQL workflow permissions already correctly configured - no changes needed

[Copilot]

Summary

This PR addresses the security audit for CodeQL workflow permissions as requested in the issue. After thorough analysis, no changes were required as the repository is already properly configured.

Findings

✅ CodeQL Workflow Already Compliant

The codeql-analysis.yml workflow already has the correct permissions:

permissions:
  security-events: write  # ✅ Required for github/codeql-action/analyze
  contents: read         # ✅ Standard read permission

✅ All Workflows Have Proper Permissions

Analyzed all 16 GitHub workflow files and confirmed they all have appropriate root-level permissions blocks:

• 14 workflows correctly use permissions: contents: read
• 2 workflows correctly use permissions: read-all (ossf-scorecard.yml, sbom.yml)
• 0 workflows missing permissions blocks

Repository Status

The repository is fully compliant with OpenSSF Scorecard token-permissions requirements. The CodeQL workflow was already configured with the necessary security-events: write permission that enables the github/codeql-action/analyze action to upload security findings.

Verification

Verified using automated analysis script that checked:

• Root-level permissions block existence in all workflows
• Correct formatting and placement of permissions
• Specific CodeQL requirements for security-events access

No security vulnerabilities found related to workflow token permissions.

Fixes #28.
