Fixes #14904.
testTrackingDump()signaled task startup before the blocking virtual threads necessarily reachedWAITING, and its 10-second timeout allowed tracked tasks to finish before both dumps completed.Use one task instance per virtual thread, wait for the two blocking tasks to reach
WAITING, and keep all four tasks alive until both dumps are complete. This preserves the existing assertions for thread state, carrier information, and detailed stack frames.Tests:

I used OpenAI GPT-5.6 and Kimi K3 to assist with issue analysis and drafting the implementation and tests. I reviewed and verified the final changes.
