Simplify

Hi @dignifiedquire , long time no see. I've been playing with TUI and I got enchanted with your dreamer project.

Days hack result here - https://gitlab.com/BrightOpen/BackYard/termit/-/tree/develop/examples/dech

I have radically trimmed down on complexity while still getting some decent UI out of it. I've removed tokio runtime dependency form dreamer code and removed all the RwLocks. Unfortunately not form DC core itself... The gist is to convert long running futures into short lived iterations and let the app loop iterate over it.

Good luck and looking forward to a pure rust DC! :D

The issue names no project files or tests; start by reviewing the dreamer code and the external examples/dech result. Compare its removal of the tokio runtime and RwLocks with the proposed short-lived future iterations and app loop. The issue does not define acceptance criteria, so confirm the intended scope and completion conditions before proceeding.
