📄 Description

Add --pressure-iterations to bound the pressure-test loop (upstream's --do-pressure-test runs int(1e9) seeds, i.e. until killed; 0 keeps that behavior), with argument validation. Add a barrier before dist.destroy_process_group() so a fast rank cannot tear down the TCPStore while slower ranks are still in destroy.
