48-48: 建议添加更多的规范化测试场景
当前仅测试了数字提取的场景，建议增加更多边界情况的测试，如：
- 空字符串处理
- null/undefined 处理
- 多个数字的情况
示例代码：
it('normalize edge cases', async () => {
const fn = jest.fn();
const { container } = render(
<Form onFieldsChange={fn}>
<InfoField name="test" normalize={value => value?.replace(/\D/g, '') || undefined} />
</Form>
);
// 测试空字符串
await changeValue(getInput(container), '');
expect(fn).toHaveBeenCalledTimes(0);
// 测试多个数字
await changeValue(getInput(container), 'a1b2c3');
expect(fn).toHaveBeenCalledTimes(1);
expect(fn.mock.calls[0][0][0].value).toBe('123');
});52-55: 建议优化测试断言的可读性
当前的断言虽然正确，但可以通过添加更具描述性的错误信息来提高可维护性。
建议修改为：
- expect(fn).toHaveBeenCalledTimes(0);
+ expect(fn).toHaveBeenCalledTimes(0, '非数字输入不应触发 onFieldsChange');
- expect(fn).toHaveBeenCalledTimes(1);
+ expect(fn).toHaveBeenCalledTimes(1, '数字输入应该触发一次 onFieldsChange');src/Field.tsx (1)
623-629: 优化：添加值相等性检查以避免不必要的更新
这个改动通过在dispatch之前添加值相等性检查来优化性能，避免了当新值与当前值相同时触发不必要的更新。这是一个很好的优化。
不过需要注意的是，由于使用了深度相等性检查（isEqual），对于大型对象或频繁更新的场景可能会带来轻微的性能开销。在大多数情况下，这种权衡是值得的，因为它可以避免更昂贵的重渲染操作。
考虑在处理大型对象值时添加性能监控，以确保深度相等性检查不会成为性能瓶颈。可以通过以下方式实现：
+ // For large objects, consider using reference equality first
+ if (newValue === value) {
+ return;
+ }
if (!isEqual(newValue, value)) {
dispatch({
type: 'updateValue',
namePath,
value: newValue,
});

44-56: 测试用例设计合理，验证了值变更的边界情况
测试用例很好地验证了表单字段在规范化处理后，只有在实际值发生变化时才会触发 onFieldsChange 回调。
