Proposed changes

The API wrote every generated floor to a file in the working directory that was never cleaned up, so it now returns the JSON directly with the same body and headers as before. The CORS setup reflected any origin while allowing credentials, which the API does not need, so credentials are now disabled. Each generator now uses its own random number generator instead of the global one, which keeps all seeds producing identical floors and makes concurrent generation safe. With that in place, the generation endpoints are synchronous so FastAPI runs them in its thread pool instead of blocking the event loop.
