- PromptTracker: the cleanup thread waits on a stop event instead of
time.sleep; new shutdown(timeout=2) joins it and returns whether it ended.
- ImageGenerationHandler.shutdown(timeout=5) now joins the worker and
returns a bool; new close() is final: schedule() refuses and a sealed
run's history re-check is dropped, so no worker restarts afterwards.
- ImageMonitor.stop_monitoring(timeout=5) closes the handler first, then
stops and joins the watchdog observer within one deadline.
- Every test that builds a real tracker, handler or monitor ends with its
final stop and an assertion, before its folder and databases go.
- #370: the wrapper/session history test drains before dispose(); the
held-write bound test uses 30 s ceilings instead of tight wall clocks.
