♻️ refactor(agent): 拆分 agentsvc，并增强 quicknote/outbox 注释与可维护性 - 📦 将 Agent 服务实现从 `service` 根目录迁移到 `service/agentsvc`，包含 `agent.go`、`agent_quick_note.go` 及相关测试 - 🔌 新增 service 层兼容桥接 `agent_bridge.go`，保持 `service.NewAgentService` 与 `*service.AgentService` 现有调用方式不变 - 📝 为 `quicknote` 补充高密度中文步骤化注释，覆盖 `graph` / `runner` / `nodes` / `tool` / `state` / `prompt`，明确职责边界、分支条件、重试与兜底策略 - 🧭 为 `infra/outbox` 与 service agent 链路补充详细中文注释，覆盖状态机流转、幂等处理、失败回写与异步持久化语义 - ✅ 统一格式化相关文件，并通过全量后端测试：`go test ./...` 📝 chore(docs): 更新 AGENTS.md 注释强制规范 - 📚 追加“注释规范（强制）”与“注释风格示例” - ✍️ 明确复杂逻辑必须使用步骤化注释、跨文件调用需写调用目的、注释需同步维护
