Summary
When a historical opponent checkpoint is swapped in, reset every CPU environment assigned to that policy before the next rollout. Clear environment boundaries, recurrent state, reward state, and terminal state, then upload the refreshed buffers so episodes cannot span two different opponent policies.
Fixes #620.
