[Feature] 建议文档中状态管理部分加上异步方法带参数的例子

建议在文档上加上状态管理effect方法中带参数的例子，我看文档下意识以为直接写参数就能调用，然而还要包一层payload


Start in the documentation's state-management section and review the effect examples, focusing on the case where an asynchronous method receives an argument. Done when the docs clearly show the payload-wrapping pattern and how to invoke the method with a parameter.
