Problem

Rake apps can't show system notifications, such as "export finished" or "update ready". GPUI Kit's notification component is an in-app toast, not an OS notification.

Existing pieces

gpui-pre already has show_system_notification, dismiss_system_notification and on_system_notification_response. It has implementations for macOS (UNUserNotificationCenter), Windows and Linux, but not for Web. Rake's part is to integrate these, not to write platform code.

Proposal

Add a platform service that wraps the GPUI API:

Clicking a notification activates the app and delivers a payload the app chose, through the same path as URL activation, so routing and commands handle it.
Permission state is visible to the app, and denial is a normal result, not an error.
On Web, add an implementation using the browser Notification API, requested from a user event. Web is the one platform gpui-pre doesn't cover.
Document packaging requirements. macOS needs a signed bundle with an identifier, and Windows needs the app identity the installers set up. Rake's distribution pipeline already produces both.

Out of scope

Push notifications from a server.
Rich actions and inline replies. These could come later.

Done when

A packaged example posts a notification on macOS, Windows, Linux and Web, and clicking it reaches the app with its payload.
Tests cover running without permission and running unpackaged, where macOS can't show notifications.
Docs list each platform's requirements and limits.

Depends on

The move from GPUI CE to gpui-pre.
