feat: 将 demo 项目转化为 HTTP 拨测监控工具

新增 YAML 配置解析（Bun 内置 YAML）、SQLite 数据存储（bun:sqlite）、按 interval 分组并发拨测引擎、REST API（/api/summary、/api/targets、/api/targets/:id/history、/api/targets/:id/trend）、React 前端 Dashboard（统计卡片、目标表格、可展开详情面板、recharts 趋势图）。CLI 简化为仅接受配置文件路径。移除 /api/demo 路由和相关 demo 代码。保留 /health、静态资源服务和 SPA fallback。

 # Gateway Checker

-基于 Bun + TypeScript 的前后端一体化 demo。开发期使用 Vite + React 提供前端 HMR，后端由 Bun 提供 API；生产期先构建前端静态资源，再将前端资源和 Bun 后端打包为单个 executable。
+基于 Bun + TypeScript 的 HTTP 拨测监控工具。通过 YAML 配置文件定义拨测目标，后端按配置定时并发拨测，结果持久化到本地 SQLite，前端 Dashboard 展示各目标实时状态、可用率、延迟趋势等。

-## 开发命令
+## 快速开始

 ```bash
 bun install
-bun run dev
+cp probes.example.yaml probes.yaml
+bun run dev probes.yaml
 ```

-`bun run dev` 会同时启动：
-
- Bun 后端：默认 `http://127.0.0.1:3000`
- Vite 前端：默认 `http://127.0.0.1:5173`
-
-开发期请打开 Vite 前端地址。前端通过相对路径 `/api/demo` 调用后端，Vite 会把 `/api/*` 代理到 Bun 后端，因此浏览器不需要 CORS 配置。
-
-全栈开发命令使用 `PORT` 作为后端端口覆盖来源，并将同一端口传给 Vite proxy：
-
-```bash
-PORT=4000 bun run dev
-```
+`bun run dev` 会同时启动 Bun 后端和 Vite 前端。开发期请打开 Vite 前端地址 `http://127.0.0.1:5173`。

 也可以分别运行：

 ```bash
-bun run dev:server
+bun run dev:server probes.yaml
 bun run dev:web
 ```

-分别运行时，若后端不是默认 `3000` 端口，需要为 Vite 指定同一个后端端口：
+## 配置文件

-```bash
-PORT=4000 bun run dev:server
-BACKEND_PORT=4000 bun run dev:web
+程序通过 YAML 配置文件定义所有运行参数：
+
+```yaml
+server:
+  host: "127.0.0.1"
+  port: 3000
+  dataDir: "./data"
+
+defaults:
+  interval: "30s"
+  timeout: "10s"
+  method: "GET"
+

+    url: "https://httpbin.org/post"
+    method: "POST"
+    headers:
+      Content-Type: "application/json"
+    body: '{"ping": true}'
+    expect:
+      status: [200]
+      maxLatencyMs: 5000
 ```

+
+#### Scenario: 请求超时

+- **THEN** 系统 SHALL 中止该请求，记录为失败并标注超时错误
+
+#### Scenario: 请求在超时前完成
+- **WHEN** 拨测请求在 timeout 时间内收到响应
+- **THEN** 系统 SHALL 正常记录响应结果
+
+### Requirement: expect 校验
+系统 SHALL 在拨测完成后根据目标的 expect 配置校验响应，校验结果记入 check result。
+
+#### Scenario: 校验状态码
+- **WHEN** 目标配置了 `expect.status: [200, 201]`

+
+#### Scenario: 校验延迟阈值
