Add delays between tests

Introduce automatic delay between test executions in the test runner to prevent rate limiting. Added a delayBetweenTests config (default 2.5s), a delay() helper, and updated runSuite to wait between tests. This helps avoid "Too many submissions in a short time" errors during test runs.
