合并 origin/master：策划附件导入接入策划聊天入口

- 保留 DirectProject 独立聊天容器与 Supervisor 退役结果，不为冲突恢复运行时兼容分支
- 策划工作区文件导入接入 PlanningChatView 输入盒，导入期间暂缓发送、阶段批准、澄清与重试
- 工作台壳按项目记录导入进行态，导入未完成时不切换游戏运行态并提示等待
- 首页策划附件导入结果落到工作台 fileImportNotice 提示条，可单独关闭
- 设计态输入盒样式选择器由 project-supervisor-* 收敛为 project-chat-*
- 策划导入回归用例适配退役后的 harness 与 chatProps 命名

 ## 项目开发对话（DirectProject）
 
+**DirectProject 专属聊天模块**:
+AGC 普通项目聊天的独立容器，拥有 DirectProject 的聊天状态、运行态订阅、历史读取、发送队列、附件和中止交互，并把聊天投影交给专属表现层渲染；它不承接 Supervisor、Design Agent 或 Planning V2 的运行态。
+_Avoid_: 把 DirectProject 作为项目总控聊天的一个布尔分支、把四种 Agent 会话抽象成同一事实源
+
+**项目工作台布局**:
+承载本地项目的资源工作区、项目级工具和独立聊天产品路径的外层界面；布局拥有跨面板的账户/钱包入口，聊天模块只负责项目对话，不嵌套账户展示。
+_Avoid_: 把钱包入口塞进聊天设置、让聊天组件拥有工作台级账户状态
+
 **项目对话历史**:
 AGC 本地项目内 Codex 原始对话条目的持久集合，是聊天展示、工具卡片和线程恢复注入的唯一持久事实源。
 _Avoid_: 会话缓存、展示态历史、按 UI 需要另存的对话副本
