fix #19 - Enable GitHub CodeQL scanning

[fantonangeli]

Closes #19

Summary

Configure GitHub’s CodeQL code scanning for this repository to analyze the JavaScript/TypeScript codebase, catch common security issues early, and surface findings in the repo Security → Code scanning alerts.

Goals

• Enable CodeQL analysis for JS/TS to detect common vulnerabilities and insecure patterns.
• Run analysis automatically via GitHub Actions and publish results to the Security tab.
• Keep configuration lightweight and maintainable for an OSS repo.

Non-Goals

• Custom CodeQL queries on day one.
• Scanning non-JS/TS languages unless required.
• Treating CodeQL as a replacement for unit tests/linting.

Notes:

• I enabled the CodeQL scan for TS/JS files and also for GH Actions.
  The scan found 2 medium issues in 2 CIs and I fixed them in this PR:
  • .github/workflows/ci_check_license_headers.yaml
  • .github/workflows/sync-issues-to-project.yml (CC @dgutierr )

Preview:

I created 2 PRs to test the result on my fork:

• Safe PR which is green: DO NOT MERGE: Safe pr fantonangeli/serverlessworkflow-editor#9
• Unsafe PR which is red with report: DO NOT MERGE: Testing vulnerability checks fantonangeli/serverlessworkflow-editor#8

You are seeing this message because GitHub Code Scanning has recently been set up for this repository, or this pull request contains the workflow file for the Code Scanning tool.

What Enabling Code Scanning Means:

• The 'Security' tab will display more code scanning analysis results (e.g., for the default branch).
• Depending on your configuration and choice of analysis tool, future pull requests will be annotated with code scanning analysis results.
• You will be able to see the analysis results for the pull request's branch on this overview once the scans have completed and the checks have passed.
