feat(通知): 系统级 Webhook 通知子系统（事件目录 + 可插拔适配器 + 防刷屏）
平台此前出了问题只能靠人盯页面。现在各组件统一走 `notifier.notify(事件, **字段)`， 推到企业微信 / 自建服务；**所有可通知点都登记进事件目录，默认全关，用户按 webhook 勾选**。 ## 架构（`core/notifier.py` + `core/notify_events.py`） 业务线程调 `notify()` → 只做内存操作（读配置快照/匹配订阅/入队）→ 返回； 后台 1 个 dispatcher（聚合 + 每 hook 限流 + 折叠摘要）+ 3 个 sender（真实 HTTP、退避重试） 负责真正发出去。硬约束：**notify 零 DB、零 HTTP、零阻塞、异常不冒泡**——所以任务线程里 可以直接调（不用 app_context、不用 try/except），但**必须放在所有 `with self._lock` 之外**。 - **事件目录 36 条**（任务批次/单设备/设备/Worker/业务/安装/系统/AI），支持 `task.*` 通配订阅； 语义分工避免重复告警：`worker.*` 是单次尝试级，`task.device.success/failed` 是唯一权威结论。 - **适配器可插拔**：`wecom`（markdown，按 4096 **字节**截断、超限不截半个汉字）+ `json`（模板占位符，替换值按 JSON 转义，保存前干跑校验）；钉钉/飞书留了插槽（前端置灰）。 - **防打爆四层**：聚合窗口（默认 30s，同批次合并成一条并带样本）→ 令牌桶限流（默认 18/分， 对齐企微硬限 20）→ 被限流的**折叠成摘要不丢弃** → 有界队列背压。取舍：失败通知最多延迟 一个窗口，换来群不被刷屏。 ## 安全与存储 - 配置只落 `app_meta.notify_webhooks` 一个键（**不建表** → 不涉及备份覆盖红线）。 - URL 本身就是凭据（企微 `?key=`）→ 接口回显/发送记录/日志一律 `mask_url()/scrub()`； 编辑时留空即不修改；secret 永不回显。DATA_MODEL 的明文凭据告警补上了这一条。 - 发送记录：内存环形缓冲 200 条（重启清空）+ 独立 `logs/notify.log`。 ## 接入点（每个都放在锁外、不改 return 顺序） task_manager（批次开始/结束用新增的 `_BatchTracker` 统一在 finally 计数、单设备成功/失败/ 离线/重试/停止/抢占/归还/cron 停止）、device_worker 心跳看门狗、generic 任务选择器连续失效、 apk 安装开始/完成、设备上下线（**状态沿检测**，只报新变化）、备份导出/恢复、经验巡检、 用户登录、服务启停。 ## 前端 系统 Tab 新增「通知 / Webhook」子分栏：多条 webhook 列表（URL 打码）+ 编辑弹窗（格式/URL/ 密钥/事件勾选树带 ★建议/聚合/限流/自定义模板/预览）+ 发送测试 + 发送记录。 ## 自测 - 进程内逻辑 10 组断言全绿：聚合合并、限流+折叠、无配置/全局关静默丢弃、未知事件、 内部异常不外泄、JSON 转义（标题含引号换行仍合法）、URL/异常消息脱敏、配置校验。 - 端到端（假 webhook 接收端）17 项断言全绿：真实事件投递（user.login / task.batch.no_device）、 企微请求体形状、**HTTP 200 + errcode 93000 判为失败**、500 重试 3 次、记录里 URL 打码。 - 韧性：webhook 指向黑洞地址时登录耗时 100~114ms（基线 107~133ms，**异步隔离生效**）； 配置写成坏 JSON 服务照常启动、通知静默不发、日志有 error（服务端实测后已复原）。 - 页面：系统 → 通知 面板/弹窗/36 个事件复选框/预览全部正常，无 JS 报错。 - 自测数据已清理（webhook、自建任务、写坏又复原的配置键）。 文档：新增 doc/NOTIFY.md（事件表/配置/格式约束/防刷屏/加事件三步骤/排障）并登记进 doc/README； API.md §2.11；DATA_MODEL 的 app_meta 键表与明文凭据告警；ARCHITECTURE 线程表/分层/扩展点； 根 README 功能索引与日志表。

"""Webhook 通知运行时：平台各组件通过 `notify(event, **fields)` 发通知。
|
||||
|
||||
## 设计底线（改动前务必先读）
|
||||
|
||||
**通知绝不能影响主流程。** `notify()` 的保证是：**零 DB 访问、零 HTTP、零阻塞、
|
||||
异常绝不冒泡**——它只做「读内存配置快照 → 匹配订阅 → 丢进队列」这几步内存操作，
|
||||
真正发 HTTP 的是后台 daemon 线程。所以：
|
||||
|
||||
- 任务线程里可以直接调，**不用包 app_context**、不用 try/except（notify 自己兜）
|
||||
- 但**必须放在所有 `with self._lock` 之外**（锁内只做状态变更），别让通知拖住调度锁
|
||||
- 任何一处 notify 出问题，只会在日志里看到警告，任务照跑
|
||||
|
||||
## 数据流
|
||||
|
||||
notify() ──入队──> _event_q ──> notify-dispatcher（1 线程）
|
||||
① 聚合：同 (hook, 事件, 聚合键) 窗口内合并
|
||||
② 限流：每 hook 令牌桶（默认 18/分）
|
||||
③ 折叠：被限流的不丢，压成摘要（最多 60s 一条）
|
||||
└──> _send_q ──> notify-sender × 3（真实 HTTP）
|
||||
└──> 环形缓冲 + logs/notify.log
|
||||
|
||||
防打爆四层（聚合/限流/折叠/背压）的取舍：失败通知最多延迟一个聚合窗口（默认 30s），
|
||||
换来群不被刷屏——**刷屏会让通知彻底失效**。
|
||||
|
||||
## 配置
|
||||
|
||||
只落 `app_meta.notify_webhooks` 一个键（JSON），**不新建表**（因此不涉及备份覆盖红线）。
|
||||
读写只走 `core.db_config.meta_get/meta_set`（方言中立；`app_meta.key` 是 MySQL 保留字）。
|
||||
URL 里带凭据（企微 `?key=`），对外一律 `mask_url()`，日志/异常消息过 `scrub()`。
