// TestAutoUpdatePollerStartStopIdempotent proves the poller's goroutine
// ownership is clean: Start/Stop are each idempotent and Stop drains the loop
// (goleak's TestMain catches a leaked poller goroutine). The Service has no
// marketplace attached, so the immediate sweep on Start is a no-op — this test
// exercises the lifecycle, not the update logic (covered by RunAutoUpdatePass
// tests, driven directly rather than through the timer).
