fix: blacklist call-status noise (telecom / AI-call) via bl v3

Incoming calls are already handled by PhoneCallMonitor (pkg=phone_call);
com.android.server.telecom and com.xiaomi.aiasst.service emit redundant
in-call status notices. Add them to default blacklist (bl_version 3),
migrated into existing users' blacklist (add-only).

 ### 包结构 `com.a2i.forwarder`
 
 | 文件 | 职责 |
 |---|---|
-| `A2iApp.kt` | `Application` 单例；持有全局 `appScope` 和三个 Store（`settings`、`appRules`、`logStore`）。Store 都用 `MutableStateFlow`，UI 通过 `collectAsState()` 订阅。 |
+| `A2iApp.kt` | `Application` 单例；持有全局 `appScope`（`SupervisorJob+Dispatchers.Default`）与全局组件：三个 Store（`settings`/`appRules`/`logStore`）+ 监听类（`phoneCallMonitor`/`connectivityMonitor`/`carrierBalanceQuery`/`smsForwarder`/`updateChecker`）。全部经 `A2iApp.instance.xxx` 访问，`onCreate` 构造并 `start()`。UI 通过 `collectAsState()` 订阅 Store 的 `StateFlow`。 |
 | `service/NotifyListenerService.kt` | `NotificationListenerService` 实现；每条通知调 `processor.process()`，过滤后推送。 |
 | `core/NotificationProcessor.kt` | **核心决策点**。包含 LRU 去重缓存（5s）、脱敏检测（`*****` → 回退到 `tickerText`）、系统状态消息过滤、广告过滤、验证码提取、特殊 App 解析。返回 `Decision(message?, reason, appLabel, code)`。 |
 | `core/CodeExtractor.kt` | 三段正则：关键词+数字、数字+关键词、纯数字 4-8 位。检测到全 `*****` 时直接返回 null。 |
 | `core/AdFilter.kt` | 内置营销关键词 + 用户自定义关键词（`settings.adKeywords`）。 |
 | `core/AppParsers.kt` | 微信/QQ/Telegram 的 `clickUrl` 映射 + 重要消息关键词（@我、验证码、通话等）。 |

 | `core/RetryWorker.kt` | WorkManager 周期任务，每 15 分钟重发 `pending` 队列中的失败消息。 |
 | `core/LogStore.kt` | 最近 300 条日志 + 失败重发队列（≤100）。DataStore 持久化。 |
 | `core/IconExporter.kt` | 一键导出所有已安装 App 图标到用户选择的 SAF 目录（用于部署到 iOS Bark 图床）。 |
+| `core/PhoneCallMonitor.kt` | 轮询 `TelephonyManager.getCallState()`（800ms）感知来电/未接来电，构造 Decision 推送。绕过 MIUI 不向第三方监听器分发系统电话通知的限制。 |
+| `core/ConnectivityMonitor.kt` | `ConnectivityManager` + `NetworkCallback`，暴露 `isOnline: StateFlow<Boolean>`，供离线兜底判断。 |
+| `core/CarrierDetector.kt` | SIM MCC+MNC 映射到运营商（移动/联通/电信/广电），供短信兜底发免费查询码。 |
+| `core/CarrierBalanceQuery.kt` | 向运营商服务号发查询短信、解析回执余量、余额≤5 自动挂起。 |
+| `core/SmsFallbackForwarder.kt` | 断网时把紧要通知（验证码/来电）用短信发到 iPhone，5 分钟限频 + 余额检查。 |
+| `core/UpdateChecker.kt` | 查 GitHub Releases 最新版（24h 节流）→ 语义比较 → 下载 APK → FileProvider 调起系统安装器。 |
 | `store/SettingsStore.kt` | Bark 服务器列表、全局开关、广告关键词等。`MutableStateFlow` + DataStore。 |
-| `store/AppRulesStore.kt` | 黑/白名单模式 + 默认黑名单（系统 App + 三星剪贴板/键盘 + GMS）。 |
+| `store/AppRulesStore.kt` | 黑/白名单模式 + 默认黑名单（系统 App + 输入法 + 三星剪贴板/键盘 + GMS + 录音机/相册/查找/密码管理 + 通话管理/AI通话）；默认黑名单带版本号 `bl_version`，升级时把新增噪音包合并进老用户黑名单（只增不删）。 |
 | `ui/nav/AppNav.kt` | 4 个底部 Tab + 日志页。 |
 | `ui/theme/*` | 固定品牌配色（`Color.kt`）、自定义 `Typography`（`Type.kt`），`A2iTheme` 关闭动态取色、统一深浅色方案（`Theme.kt`）。 |
-| `ui/screens/*.kt` | HomeScreen（品牌横幅 + 运行状态面板 + 统计指标）、AppManageScreen、FilterScreen、SettingsScreen、LogScreen。 |
+| `ui/screens/*.kt` | HomeScreen（品牌横幅 + 运行状态 + 统计 + 更新横幅 + 短信挂起提醒）、AppManageScreen、FilterScreen、SettingsScreen（Bark 服务 / 应用图标 / 断网短信兜底 / 关于与更新）、LogScreen、UpdateDialog（应用内更新弹窗）。 |
 | `ui/Components.kt` | 共享 UI 组件层：`ScreenTitle`、`SectionCard`、`SwitchRow`、`ClickRow`、`IconBox`、`StatusBadge`、`MetricBlock`，以及 `appVersionName(context)`、`drawableToImageBitmap(d)`、`isNotificationListenerEnabled(context)` 工具函数。 |

+## 自建 Bark 服务（可选）
+
+a2i 默认用 Bark 官方服务器（`https://api.day.app`），免费够用。如果想完全自控、不限速、不依赖第三方，可以自建 Bark Server。下面是三种零成本方案：
+
+### 方案 1：Vercel 云托管（最适合新手）
+
+把 Bark 后端跑在 Vercel 的 Serverless 上，每次推送触发一个云函数，不挂进程、完全免费。
+
+- 平台：[Vercel](https://vercel.com) · 代码：[GitHub](https://github.com)
+- 在 GitHub 搜索 `bark-server-vercel`，项目 README 里通常有 **Deploy with Vercel** 按钮，一键克隆部署
+
+### 方案 2：Cloudflare Workers（最稳定）
+
+把轻量 JS 转发代码部署到 Cloudflare 全球边缘节点，免费额度每天 10 万次请求，个人用属于「溢出」状态。
+
+- 平台：[Cloudflare](https://www.cloudflare.com)
+- 在 GitHub 搜索 `bark-server-cloudflare` 或 `bark cloudflare worker`，在 Cloudflare 后台新建 Worker 粘贴脚本保存即可
+
+### 方案 3：免费 VPS + Docker（最高自主权）
+
+在永久免费的 Linux 虚拟机上用 Docker 跑官方 bark-server。
+
+- 官方服务端：[finab/bark-server](https://github.com/finab/bark-server)
+- 反向代理 + 免费 HTTPS 证书：[Nginx Proxy Manager](https://nginxproxymanager.com)
+- 免费 VPS：[Oracle Cloud 永久免费层](https://www.oracle.com/cloud/free/)、[AWS 一年免费套餐](https://aws.amazon.com/free/)
+
+### ⚠️ 防坑提示
+
+国内网络下，Vercel 的 `*.vercel.app` 和 Cloudflare 的 `*.workers.dev` 二级域名可能间歇性无法访问。**终极方案**：注册一个便宜的个人域名（或找免费域名），解析托管到 Cloudflare，然后把 Vercel / Worker 绑到**自定义域名**上——既稳定又秒达。

+自建完成后，在「设置 → Bark 服务器」里填自建地址即可。
