Version: 0.9.52.dev.260428

后端：
1. 工具结果结构化切流继续推进：schedule 读工具改为“父包 adapter + 子包 view builder”，`queue_pop_head` / `queue_skip_head` 脱离 legacy wrapper，`analyze_health` / `analyze_rhythm` 补齐 `schedule.analysis_result` 诊断卡片。
2. 非 schedule 工具补齐专属结果协议：`web_search` / `web_fetch`、`upsert_task_class`、`context_tools_add` / `context_tools_remove` 全部接入结构化 `ResultView`，注册表继续去 legacy wrapper，同时保持原始 `ObservationText` 供模型链路复用。
3. 工具展示细节继续收口：参数本地化补齐 `domain` / `packs` / `mode` / `all`，deliver 阶段补发段落分隔，避免 execute 与总结正文黏连。

前端：
4. `ToolCardRenderer` 升级为多协议通用渲染器，补齐 read / analysis / web / taskclass / context 卡片渲染、参数折叠区、未知协议兜底与操作明细展示。
5. `AssistantPanel` 修正 `tool_result` 结果回填与卡片布局宽度问题，并新增结构化卡片 fixture / mock 调试入口，便于整体验收。

仓库：
6. 更新工具结果结构化交接文档，补记第四批切流范围、当前切流点与后续收尾建议。
