Write high scores to HTTP

這個 Issue 沒有描述。

The issue title suggests adding HTTP functionality to write high scores. Look for existing game state and score handling code, likely in a module like GameState or Logic. Research how HTTP requests are made in Haskell (e.g., using http-conduit or wai) and where to integrate this. Check if there's already a server setup or if one needs to be added. Determine what 'done' looks like: high scores are successfully posted to an HTTP endpoint.
