feat: 落地 V1 全部源码 — WebSocket 通知 + 应用内历史查看

17 个源文件 + .gitignore + 默认 config.json 模板,严格按方案文档第 6 节实现。

用户核心场景:

- Windows 接收 Gotify 通知(WS /stream → AppNotificationBuilder)

- 应用内查看历史消息(打开 MainWindow 触发 GetRecentMessagesAsync,实时通过 MessageReceived 事件追加)

- 列表条目双击打开 extras.client::notification.click.url

关键变更点:

- GotifyMessage.Extras 类型由 Dictionary<string,object> 改为 Dictionary<string,JsonElement>,避免 System.Text.Json 反序列化时丢失嵌套结构

- 新增 HistoryConfig.ViewerLimit(默认 50,UI 硬上限 200)

- GotifyApiService.GetRecentMessagesAsync:since=0 拉最近 N 条,OrderByDescending(Id) 保证顺序

- GotifyWebSocketService 新增 MessageReceived 事件,MainWindow 用 Dispatcher.Invoke 切回 UI 线程追加

- NotificationService.AddArgument('url=...') 透传 click URL 给 OnNotificationInvoked

- MainWindow.xaml 增加 ListView + 刷新按钮,使用 ObservableCollection<GotifyMessage>

- 默认 config.json 用 https://gotify.example.com 占位 URL,ClientToken 留空,首启动自动写入 %LOCALAPPDATA%

依赖:Microsoft.WindowsAppSDK 2.4.0(方案文档固定版本)。

构建:本机 .NET 8 SDK 未安装,build 待用户在装好 SDK 后执行: dotnet restore && dotnet build -c Release
