Add GitHub Actions workflow to run tests on pull requests

[Copilot]

This PR adds a GitHub Actions workflow that automatically runs the test suite on all pull requests targeting the master and develop branches.

What's Changed

Added .github/workflows/test.yml which:

• Triggers on pull requests to the master and develop branches
• Uses Node.js 20 (matching the project's requirements)
• Installs dependencies with npm caching for faster runs
• Verifies TypeScript compilation is up to date - Runs npm run tsc and fails if any files are modified, ensuring developers commit generated JavaScript files
• Creates the required config.json file for tests
• Runs the complete test suite via npm test, including:
  • TypeScript compilation
  • StandardJS linting
  • Mocha unit tests (121 tests covering download, filesystem, interpreter, middleware, utilities, and webhook modules)

Why This Change?

Currently, the project relies on manual testing or external CI systems. This workflow provides automated quality checks directly in GitHub, making it easier to catch issues early in the development process and ensuring all PRs meet the project's quality standards before merging.

The TypeScript compilation check ensures that all generated JavaScript files from TypeScript sources are kept in sync and committed, preventing issues where TypeScript changes are made but the compiled output is not updated in the repository.

Testing

The workflow configuration has been validated for:

• ✅ Correct YAML syntax
• ✅ Uses latest stable GitHub Actions (checkout@v4, setup-node@v4)
• ✅ Follows the same test setup pattern as the existing CircleCI configuration
• ✅ All 121 existing tests pass locally with this setup
• ✅ TypeScript compilation check correctly identifies uncommitted changes

The workflow will be automatically tested when this PR is merged and subsequent PRs are opened.

@copilot also add a check that tsc has been run correcly: there should be no diffing files after running npm run tsc

Added a check to verify TypeScript compilation is up to date. The workflow now runs npm run tsc and fails if there are any uncommitted changes, ensuring developers commit generated files. See commit 031f0e3.

[nitpick] The shell script logic is embedded in the YAML workflow. Consider extracting this into a separate script file for better readability and maintainability.
