DO NOT MERGE: negative control — restore max_cached_workflows=0

Restore `max_cached_workflows=0` on the parametrized 1000x stress test
to verify the hypothesis from the other direction: with cache=0 in
place, Windows 3.10 should reproduce the [TMPRL1101] deadlock flake
within 1000 iterations.

Previous run (cache=0 removed) passed 1000/1000 on every matrix entry.
Expectation: this run will fail on Windows 3.10.
