Verify CodeQL workflow permissions are correctly configured

[Copilot]

This PR addresses the security requirement to ensure CodeQL workflows have proper permissions configuration.

Analysis Results

After thoroughly examining the repository's GitHub workflows, I found that the CodeQL permission configuration is already correct and follows security best practices:

Workflows Analyzed

• .github/workflows/codeql.yml - Uses github/codeql-action/analyze ✅
• .github/workflows/ossf-scorecard.yml - Uses github/codeql-action/upload-sarif (not affected by this requirement)

Current Permission Configuration

The codeql.yml workflow correctly has:

• Root-level permissions: Only contents: read (minimal necessary permissions)
• Job-level permissions for the analyze job:

  permissions:
    contents: read
    actions: read  # for github/codeql-action/init to get workflow details
    security-events: write  # for github/codeql-action/analyze to upload SARIF results

Security Compliance

✅ The security-events: write permission is properly defined at the job-level, not at the root-level
✅ This follows the principle of least privilege by only granting the permission where it's needed
✅ Other jobs in the workflow (if any) don't inherit unnecessary permissions

Conclusion

No code changes were required as the repository already meets the security requirements. The CodeQL workflow correctly implements job-level permissions for the github/codeql-action/analyze action.

Fixes #30.
