"""Lifespan scan-loop test (v1.1.0 defect fix).

`scan_and_enqueue_tasks` previously had no scheduler — the OpenClaw Worker
wakes every minute but could never pull a task. The lifespan now starts an
asyncio background task that scans executing evals every 60s. This test
verifies that on application startup the scan is actually invoked.
