`ThreadedDispatcher::run_until` - the completion mechanism under `BenchAppContext` async task benchmarks (`bench_task` / `bench_batched_task`, added in #62180) - drained the entire main queue before checking its readiness predicate. Main-thread work that re-queues itself (an idle-time sweep, a polling loop) keeps the queue non-empty until it finishes every iteration, so a task benchmark's measured interval silently extended past the awaited task's completion until all such deferred work settled. Benchmarks of UI workloads that schedule follow-up idle work could report several times their true completion latency. This changes `run_until` to step main-thread runnables one at a time and check readiness before each, so it returns at the completion it awaits rather than at queue quiescence, making async task benchmarks more accurate. The regression test spawns a task that re-queues itself 10,000 times plus a one-shot completion task, and asserts `run_until` returns without draining the re-queued work; it fails against the previous drain-first implementation.
