new proxy implementation with Gin framework

- Created a new proxy structure under NewProxy/ using the Gin web framework.
- Added main entry point (main.go) to register and run routes.
- Implemented new route handlers for:
 > Status — monitors active downloads and total data transferred.
 > Forward — handles proxy forwarding logic.
 > Builds — manages build-related requests.
