The fixed 5-update budget in `pull_failure_sets_error_status` was
the last test still subject to the AsyncComputeTaskPool starvation
mode that v0.19.0's auto-save fix already cleared. Under heavy
parallel cargo-test load, 5 updates wasn't always enough for the
failing pull task to surface its Err and flip
SyncStatusResource to Error.
Pumps updates in a loop bounded by a 5-second deadline (with
std::thread::yield_now between iterations to give the task pool a
chance to run), exiting as soon as the status flips. Mirrors the
auto-save flake fix shape — a healthy run hits the assertion in a
handful of frames, while a starved run gets the budget it needs
without hanging the suite.
