Easily Sync Character Data

[ianmacartney]

Let's make it easier to jam on Character data.

Problem:

You have to run init (often through npm run dev) for the world to add new characters. Once they're there, you can't re-sync the json.

Solutions:

• Edit the data directly in the dashboard, under agentDescriptions. This will not update in the UI (see playerDescriptions for that) but will be used for prompts.
• Let's add a function to re-sync the data from the init script with the active agents. You can run it when you edit.
• Or have a way to export the data from the dashboard into a json file so you can capture changes
