rules: add test-determinism (condition-based client pumping, no thread+sleep)feat/rml-compositing
Crystallizes the scar behind the Wave-1b de-flake: headless integration tests
must drive a real client by condition-based event-loop pumping, never a free-
running thread + time budget (which starves under load -> sentinel reads / silent
skips / drifting assertion count).
