PR Overview
This PR fixes an issue where the Drawer component was not obtaining the correct width during drag-resize operations by switching from state to a ref for tracking the latest drag size.
- Changed handleMousemove and handleMouseup to use useCallback for improved performance and stability.
- Introduced a ref (dragSizeNumberRef) to store the current drag size, ensuring the handleMouseup callback accesses the latest value.

- [nitpick] The variable name 'dragSizeNumberRef' is a bit verbose. Consider renaming it to 'dragSizeRef' for improved readability.
const dragSizeNumberRef = useRef<number>(0);
const dragSizeRef = useRef<number>(0); 感觉变量名可以这个 |

🤔 这个 PR 的性质是？

💡 需求背景和解决方案
在
useDrag.ts文件中， handleMouseup 函数中的 dragSizeValue 每次取值不正确的问题，是由于 dragSizeValue 的状态更新不及时导致的。 useState 的更新是异步的，因此在 handleMouseup 中直接使用 dragSizeValue 会导致获取到的值不是最新的。解决方案是使用 useRef 来存储最新的 dragSizeValue ，这样可以确保在 handleMouseup 中获取到的值是最新的。
