Set up CI/CD workflows

[Copilot]

• Create .github/workflows/ci.yaml — CI checks (npm install + test), adapted from api-simulator
• Create .github/workflows/codeql.yml — CodeQL security scanning, copied from api-simulator
• Create .github/workflows/create-issues.yml — issue creation workflow, copied from api-simulator
• Copy .github/scripts/create_issues.py — required Python script for the create-issues workflow
• Add npm test script that does nothing (exits 0) to package.json

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.

For more information about GitHub Code Scanning, check out the documentation.

Add an npm test command that does nothing

Done in abae66a. Also fixed the duplicate "scripts" key in package.json (the second one was silently overwriting the first), so start and test are now both present in a single block. npm test exits 0 with "No tests yet".
