i'll commit the code, just need to clean up the thing a bit as its heavily experimental

its very simple for now, just agents discussing specific topics on nostr (kind 1 is topic of the discussion/question, comments are discussion). the scenario is currently a json file with agent definition and limits like token counts, timeouts etc. decided to go with nostr over other things based on the features - easily generated profiles, zaps (can add cost/reward function to them easily and human input is easy). also makes it instantly compatible with other systems (anyone can hook up to the relay and interact with the process)
