feat(dock): add app launch duration reporting for taskbar icons

Use AM.Identify(pidfd) for precise per-window instance mapping, read
X-linglong from desktop files, and query dpkg/linglong for package
version info. Report the data via DDE EventLogger (event ID 1000610003).

使用 pidfd 精准匹配窗口与 AM 实例，从桌面文件读取玲珑包名，
通过 dpkg/玲珑查询包版本信息，并通过 DDE EventLogger 上报数据。

Log: 新增任务栏图标启动时长上报
