Replay a recording from memory and verify it reproduces the same world-state hashes. Stands up a fresh world, restores the seed snapshot, replays every op, and checks each embedded StateHash record. Returns true if replay completed without id mismatches or hash divergences. @param data pointer to recording bytes @param size byte count of the recording @param workerCount reserved for future multithreaded replay; pass 1 for now
