In-app announcements (the tip-bar messages shown at startup) can now declare a requiresModel field. An announcement with this field set is only shown when the currently active model matches. Previously all eligible announcements were candidates regardless of the selected model.
The startup_announcement value is also now included in the init info payload sent to extensions, allowing the IDE to display the same announcement that the CLI would show.
Evidence
qCl() filter function (search for "requiresModel" in announcement filter logic) and startupAnnouncement in init payload (search for "startup_announcement")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
