…Hub Pages

- Introduced a new GitHub Actions workflow in `deploy.yml` for building and deploying static content.
- Configured the workflow to trigger on pushes to the `main` branch and allow manual execution.
- Set up jobs for running unit tests and deploying to GitHub Pages, ensuring a streamlined CI/CD process.
- Included steps for Node.js setup, dependency installation, unit testing, building the application, and deploying the built content.
