- Around line 974-1017: The test enables fake timers with vi.useFakeTimers() but
restores them unconditionally at the end, risking leakage if an assertion
throws; wrap the test body that uses vi.useFakeTimers(), the calls to
vi.advanceTimersByTimeAsync(...) and all assertions in a try block and call
vi.useRealTimers() in a finally block so timers are always restored; locate the
code around vi.useFakeTimers(), the advanceTimers calls and the final
vi.useRealTimers() to implement the try/finally.

Protect fake-timer cleanup with try/finally to avoid cross-test leakage.
If any assertion fails before Line 1016, fake timers stay enabled and may cascade failures into later tests. Wrap the body in try/finally and restore timers in finally.
