WebConnectivityAdapter class
基于浏览器 navigator.onLine 的 Web 连通性适配器 /
Web connectivity adapter backed by the browser's navigator.onLine.
浏览器无法区分 Wi-Fi / 蜂窝等具体传输类型，仅能判断「在线 / 离线」，因此在线时
返回 ['wifi']、离线时返回 ['none'] /
Browsers cannot tell Wi-Fi from cellular; they only report online / offline, so
the adapter emits ['wifi'] when online and ['none'] when offline.
直接基于 package:web 实现，避免把 connectivity_plus 引入 Web 依赖图，从而保证
包对 WebAssembly（WASM）编译友好 / Implemented directly on top of package:web
instead of connectivity_plus so the package stays WASM-compatible (the plugin's
Linux-only nm dependency would otherwise leak into the web import graph).
