/**
* Browser half of the session-notify bundle.
*
* One job: tell the user when a conversation needs attention. Three triggers —
* a conversation that stopped running, a pending tool approval, and a pending
* question or plan review — are derived from the client's own session state, and
* each one is delivered exactly once, through exactly one channel:
*
* - the Harness window not in the foreground → a system notification, raised
* through the page's Web `Notification` constructor. That is the only
* system-notification channel a plugin can reach: `@deepseek-ai/dsh-desktop-host`
* runs the Host half in a plain Node process rather than in Electron's main
* process, so the Host side has no `Notification` to call. The same Web API
* backs Windows, macOS, and Linux inside the Desktop shell, so delivery has no
* platform branch at all — only the settings row's *help text* names the
* platform's own notification settings.
* - the window in the foreground, and the finished conversation not the one on
* screen → a light in-app popup, because a desktop notification while you are
* looking at the app is noise.
*
* State comes exclusively from the slot props' standard selector hooks
* (`useSessions`, `useSessionStatus`) — the documented way for a plugin to read
* session data. Nothing here polls, folds session events, or reaches into
* another plugin. Styles are this package's own, following the shipped toast and
* switch surfaces and referencing theme tokens only, because a plugin must not
* import a Harness Client package.
*
* @module @dsh-plugin/session-notify/client
