Add CI/CD pipeline, architecture documentation, and monitoring application

- Created a GitHub Actions workflow for CI/CD to deploy to Ghyamah, including testing, building, and pushing Docker images.
- Added architecture design document for handling 15,000 requests per second, detailing system components, capacity planning, and cold start strategies.
- Introduced a Python-based uptime/latency/SSL monitor with a static dashboard, utilizing standard libraries only.
- Included Dockerfile and entrypoint script for the monitoring application, ensuring it runs as a non-root user and handles process management.
- Added a .dockerignore file to exclude unnecessary files from the Docker build context.
- Created an HTML dashboard for visualizing monitoring metrics, including uptime, latency, and SSL certificate status.
