pub fn install(window: &WebviewWindow<Wry>)Expand description
Installs the Mountain-layer debug server and stores a reference to the renderer webview window. Called once during app setup in debug builds.
Activation is gated by the unified DebugServer env var (see module
docs). When cocoon/both is selected, this function still installs
the window handle (so /eval keeps working for proxy requests) but
skips starting the Mountain HTTP listener.
