fix: Rule deps on the useWatch (#776)

* test: test driven

* test: test driven

* feat: await next frame before validation to support useWatch in rules

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* refactor: replace raf with custom delayFrame for better test control

- Replace @rc-component/util/lib/raf with custom delayFrame utility
- Export macroTask for test usage
- Add delayUtil.ts with mockable delayFrame implementation
- Update tests to use fake timers and waitFakeTime for better control
- Add jest.mock for delayUtil in test files

* chore: remove debug console.log statements

* refactor: remove macroTask export and use setTimeout in tests

* fix: remove duplicate line in mock file
