Single-image benches keep fail-fast; >8 distinct images (swe's 500
per-instance) now pull concurrently with resume state inside the run
itself -- exactly like the old auto-pull behavior, just resilient:
scoring proceeds with whatever images landed, missing ones score 0
and only a total wipeout fails the bench. Ctrl+C-safe (state file),
network recovery resumes automatically on the next run.
