Add comprehensive tests using TestBuilder pattern to verify YesTask
handling in the event loop. These tests would have caught the crash
that was fixed in the event loop's tickQueueWithCount function.

Tests cover:
- Basic YesTask event loop processing with head
- Custom string output in event loop
- YesTask cancellation/timeout scenarios
- High volume output for event loop stability
