Since the event-driven shutdown refactor (0fbb07c), the profiler main
loop is asyncio.wait_for(shutdown.wait(), timeout=interval) — no sleep
on the hot path. The four worker tests that patched asyncio.sleep to
raise CancelledError on the Nth call were silently no-op'ing and
hanging on the real 30 s wait_for timeout.
Replace the sleep patches with a shared _cancel_after helper that
patches wait_for itself. Pass interval=0 so the loop ticks without
delay between iterations.
