A reusable helper in the shared harness that drains microtasks + advances one short fake-time tick, replacing the two patterns that have repeatedly wedged the suite (and the pre-push gate) for ~10 minutes each: pumpAndSettle (loops until quiescent — hangs on perpetual animation / overlapping async) and `await Future.delayed(Duration.zero)` inside testWidgets (a real timer that never fires under fake-async). Bounded by construction — cannot hang. Co-Authored-By: Claude <noreply@anthropic.com>
