markqvist/Reticulum ? reverse-engineered prompt

Build me the Reticulum network stack in Python, as a clean, working project I can install and run locally.

It should support secure, decentralized networking over things like WiFi, LoRa, and packet radio, with automatic multi hop routing, encrypted links, unique addressing, reliable delivery, and simple request and transfer support. I want it to run in user space with no special kernel stuff, and feel easy to use for building off grid apps and tools.

Please make sure the core library, examples, and tests all work, and that the project can be installed and used from a normal Python environment. Include clear docs or a basic README style guide for how to start it, how to connect interfaces, and how to try a simple message or file transfer. If you need to check current docs or protocol details online, go ahead and look them up.
