• Implement searchMarkets.
• Map outcomes and data to UnifiedMarket format.

Currently, I'm facing an issue with the Metaculus API page. There appear to have been changes to their Swagger OpenAPI setup. Instead of displaying the Swagger documentation, it now shows the following message: "Permission Error: The API is only available to authenticated users. Please create an account and use your API token to access the API." As a result, I expect this task may take longer than initially planned.

Happy to work on this. I have opened a PR #71 for this. Would appreciate your review, sir @realfishsam
