fix(wechat): cancel sole active scheduled task in inbound without Goose

When a user has exactly one active automation task, cancel it by taskId
after listTasks instead of relying on Goose when the LLM provider fails.

 1. 先判断用户是要**创建**、**查询**、**取消**还是**更新规范**。
 2. 缺时间或缺任务内容时，一次只追问最小必要信息。
 3. **取消 / 更新**前必须先 `scheduled_task_list`，用返回的 `taskId` 操作；由你理解用户指哪一条，不要猜 titleMatch。
+   - 微信 inbound：若用户只有 1 个 active 任务，会直接取消；多个 active 任务时才进入 Goose 让你选 taskId。
 4. **更新规范**：用户补充格式标准、参考页面 URL、排版约束时，对目标任务调用 `scheduled_task_update_spec`，`mergeTaskSpec: true` 追加说明。
 5. 创建成功后，用用户能理解的话说明何时执行、执行什么、recurrence、推送通道。
 6. 若提示里给出了 `sourceMessageId`，调用 `scheduled_task_create` 时必须原样传入。
