ymlandClaude Opus 4.8 ad70b24fb6 提交2: 发布群核心功能实现
- 实现 EnsureListingConversation: 发布时建发布群,发欢迎语+二维码
- 实现 AddRenterToListingConversation: 付款后拉租客进群
- 实现 RemoveRenterFromListingConversation: 订单终态移出租客
- 实现消息可见性过滤: 租客只能看到 joined_at 之后的消息
- listing 模块注入 ListingChatCreator 接口,发布时建群
- ListingDTO 新增 listing_group_conversation_id 字段
- 付款流程改为拉租客进发布群(替代建订单群)
- 订单完成和取消时自动移出租客
- 创建 chat 适配器实现接口解耦
