fix: keep generation progress out of chat history

 - 玩法特有的生成进度只通过 `beforeExecuteAction` 与 `onActionError` 这类回调接入：compile action 发起前切到独立生成页并初始化进度，失败时把进度置为 failed。
 - compile action 成功后继续由通用控制器切到结果页，页面层只补齐生成资产数量、拼图操作记录、作品架与广场刷新等玩法差异。
 - 离开玩法流程时，先清理运行态与生成进度态，再交给通用控制器恢复创作中心，避免流式回复和进度状态在下一次创作中残留。
+- 生成进度页的阶段文本、资产完成文本、草稿写回文本只属于进度读模型和结果页状态，不属于 Agent 聊天历史。后端 compile / asset action 不再追加 `action_result` 聊天消息；前端聊天气泡只展示 `kind === "chat" | "summary" | "warning"` 的消息，历史会话中已经存在的 `action_result` 只作为兼容数据保留，不再渲染。

 - 生成中可看到独立进度页，且进度步骤随 action 完成逐步推进。
 - 拼图结果页打开时已有正式图；大鱼结果页打开时主图、动作和背景资产均已写入 `assetSlots`。
 - 前端点击生成草稿时不串行调用多个资产 action；多阶段业务编排收敛在 `server-rs`。
+- 返回 Agent 工作区后，聊天区不出现“拼图结果页草稿已生成。”“本级主图已正式生成，可在结果页继续预览。”这类生成进度页状态消息。
 - 不新增 server-node 依赖，不复活 legacy public 静态资产路径。
