Version: 0.9.75.dev.260505

后端： 1.收口阶段 6 agent 结构迁移，将 newAgent 内核与 agentsvc 编排层迁入 services/agent - 切换 Agent 启动装配与 HTTP handler 直连 agent sv，移除旧 service agent bridge - 补齐 Agent 对 memory、task、task-class、schedule 的 RPC 适配与契约字段 - 扩展 schedule、task、task-class RPC/contract 支撑 Agent 查询、写入与 provider 切流 - 更新迁移文档、README 与相关注释，明确 agent 当前切流点和剩余 memory 迁移面

+// 设计说明：
+// 1. 本轮只处理 web 工具卡片，按 AGENTS.md 的迁移约束避免同一轮跨多个能力域抽公共 toolview 层。
+// 2. 因此这里先在 web_result 包内保留最小公共 helper，保证 web_search / web_fetch 先完成切流。
+// 3. 若后续 taskclass / context 也出现同类卡片 helper，再由主代理统一评估是否下沉成公共层。
+
+// BuildResultView 统一封装 web 结果卡片结构。
+//
+// 职责边界：
+// 1. 负责把已经计算好的折叠态、展开态内容组装成标准视图。
+// 2. 负责在子包内补齐 status / status_label，避免依赖父包状态常量。
+// 3. 不负责 ToolExecutionResult 外层协议，也不改写 observation 原文。
