Verify CodeQL workflow permissions are correctly configured

[Copilot]

This PR addresses the security requirement to ensure GitHub workflow jobs that run "github/codeql-action/analyze" have correct permission configurations.

Verification Results

✅ All CodeQL workflows already meet security requirements

Analysis Summary:

• Workflows scanned: 9 total workflow files in .github/workflows/
• CodeQL analyze workflows found: 1 (.github/workflows/codeql-analysis.yml)
• Security issues found: 0

Current Permission Structure (Correct):

The codeql-analysis.yml workflow properly implements the required security pattern:

# Root-level permissions (minimal)
permissions:
  contents: read

jobs:
  analyze:
    # Job-level permissions (specific)
    permissions:
      security-events: write # for github/codeql-action/autobuild to send a status report

Security Best Practices Validated:

• ✅ security-events: write permission is defined at job-level (not root-level)
• ✅ Root-level permissions are minimal (contents: read only)
• ✅ No unnecessary permissions granted at workflow level
• ✅ Follows principle of least privilege

The CodeQL workflow was recently added and already follows the correct security pattern outlined in the issue requirements.

Fixes #17.
