Build and Push Docker Images / build-and-push (push) Successful in 39s
Refactor the xtream-proxy from a single-file Express-based server to a modular Node.js application using native http/https modules. This change introduces a major version bump to 2.0.0. - Replace `hosts.txt` with `upstreams.json` for configuration - Remove heavy dependencies (`express`, `ws`) in favor of native modules - Implement new environment variables for proxy credentials and timeouts - Add `src/` directory for modular code structure - Add `docker-compose.example.yml` for easier deployment - Update Dockerfile to support the new directory structure and environment - Improve error handling and probe logic for upstream selection
