/**
|
||
* UpdateService — 轻量自动更新检查(v0.6.4 P4-2 引入,v0.8.0 P2-3 接入 electron-updater)
|
||
*
|
||
* 双轨设计:
|
||
* 1. 手动检查(check()):feed 比对式 —— 拉取版本清单 JSON 与当前版本比较,
|
||
* 结果经 IPC 直接返回(不依赖 electron-updater,dev 模式同样可用)。
|
||
* 2. 自动更新(startAutoUpdater,v0.8.0 P2-3):生产环境接入 electron-updater
|
||
* (generic provider),启动 5s 后静默检查;available → 广播 update:status +
|
||
* 系统通知;用户触发下载安装(app:updateInstall)→ downloadAndInstall 后重启。
|
||
* 未配置 feed / dev 模式 / electron-updater 不可用时静默禁用(可用性优先)。
