## What changed? Inlined the server and client code from the Nexus SDK ## Why? The protocol has been deemed to stay experimental for a while longer and we want to get trim Nexus Go SDK to the bare minimum. ## How did you test it? - [x] built - [x] run locally and tested manually - [x] covered by existing tests - [x] added new unit test(s)
