文档先行：把 DirectProject 聊天真相源收敛的文档改到当前实现状态

- 主规范把事件模型写成 ts-rs 导出的 tagged enum，说明 seq 不下发、事件不带回合身份，并补上 ts 绑定生成与 f64 时间戳约定
- ADR 补上 tagged enum 绑定、turn id 删除、正文只增不减与回合回收、前端卡片去掉 turnId、未知类型前端丢弃
- 里程碑与实施计划同步：文件改名到 direct_thread_wire.rs，新增删回合身份与生成绑定两步，验证命令加上 export_bindings
- 工具卡片技术方案在文首加修订段：数据来源层作废，表现层契约仍然有效，DirectRuntime 的 tool-calls.jsonl 写入保留
- 对话回合唯一投影里程碑改为 superseded，列出仍然有效与已作废的分界
