Improve world prompt

[murderteeth]

• it takes GPT a long time to generate formatted responses
• the world prompt involves lots of text and a formatted output
• so right now it's constrained to GPT3 because GPT4 times out
• instead of doing it all in one prompt, use two prompts w GPT4 like this
  • full description prompt, no format
  • summary prompt, no format
  • combine into json on the api-side
