+讨论 channel 的 participant 集合继续复用现有 channel member bootstrap 逻辑：由 `plugin/core/turn-bootstrap.ts` 调用 `fetchVisibleChannelBotAccountIds(...)` 基于 Discord 可见成员与已有 account 映射发现可参与的 bot account，再交给 `initTurnOrder(...)` 建立轮转状态，而不是为 discussion 模式额外维护一套成员发现流程。

 如果轮转一圈无人发言，则 moderator 提醒发起者：
 - 若已达成目标，请写总结文档并 callback
