Michael Chus 348db35119 fix(stress): stagger john GPU launches to prevent GWS tuning contention
When 8 john processes start simultaneously they race for GPU memory during
OpenCL GWS auto-tuning. Slower devices settle on a smaller work size (~594MiB
vs 762MiB) and run at 40% instead of 100% load. Add 3s sleep between launches
so each instance finishes memory allocation before the next one starts.
