Added express as a production dependency in package.json and updated the Dockerfile to install dependencies more efficiently using npm ci when package-lock.json is present. This streamlines the build process and ensures express is available in production environments.
Introduced Dockerfile, .dockerignore, and GitHub Actions workflow for building and publishing Docker images. Added server.js as the Express entrypoint for standalone deployment. Updated README with Docker, Docker Compose, and Kubernetes deployment instructions.
