The 700ms re-poll in local-runtime-jobs.ts reached for `window.setTimeout`;
when a test left a running job in the store, the timer fired after vitest had
torn down jsdom and threw `ReferenceError: window is not defined` as an
unhandled error, failing the whole check:test:ui lane on main even though all
7808 tests passed. Use the global timer functions (identical in the renderer)
and drain the running-job state after each local-models-settings test so no
poll is armed across test boundaries.
