Subject: [PATCH] feat: position rotation every 10 games in self-play
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

--mix-rotate: 每10局轮换bot排列
[ISMCTS,ISMCTS,NEURAL] → [NEURAL,ISMCTS,ISMCTS] → [ISMCTS,NEURAL,ISMCTS]
Neural 三个位置都练到, 数据分布平衡
orchestrator改用--mix-rotate替换--mix
