Gozargah/Marzban-node ? reverse-engineered prompt

Build me a small Python service called Marzban node that can run on a server and act as a proxy node for Marzban.

I want it to be easy to install and run with Docker or as a system service, and I want a simple command line setup flow like install, install with a custom name, and a help command. It should manage the node connection, read basic config from environment or a config file, handle certificates, and start the proxy related services cleanly. If it needs current docs or setup details, look them up online.

Please include sensible defaults, clear logging, and a straightforward README with quick install and manual install steps. Make sure it works like a real server side node component, not a demo, and keep the code organized so it is easy to configure and deploy on a VPS.
