  Handler implementation for the 'list_hub_genomes' tool. It extracts the hub_url from arguments, builds the API URL for '/list/hubGenomes', and makes the request.

  elif name == "list_hub_genomes":
      params = {"hubUrl": arguments["hub_url"]}
      url = build_api_url("/list/hubGenomes", params)
      result = await make_api_request(url)
