Hooks order is changed during update

首先定位 FilterContextProvider 和 useStepFlow() API，然后在更新到 React 19 时重现 Hook 顺序警告。跟踪各次渲染之间发生变化的渲染路径，并验证在使用 useStepFlow() 的活动期间 Hooks 顺序保持稳定。

I'm trying to update to the React 19, but the following error occurs

React has detected a change in the order of Hooks called by FilterContextProvider. This will lead to bugs and errors if not fixed. For more information, read the Rules of Hooks: https://react.dev/link/rules-of-hooks

   Previous render            Next render
   ------------------------------------------------------
1. useContext                 useContext
2. useTransition              useContext

This seems to happen on any activity that calls the useStepFlow() API.
