Pull Request Overview
This PR addresses an issue where fast Chinese input on iOS in input and textarea elements causes the cursor to disappear due to debounced value updates.
- Introduces a cancelValueChange function in useValueSync to cancel pending debounce/throttle callbacks.
- Updates the useEvent signature and onInput handler to call cancelValueChange, ensuring timely cancellation during composition events.
