App Store release cards compacted; routine updates filtered from discovery

Changed

• App Store release cards in related rails and the homepage ticker now render as compact entries — app icon, name, iOS/macOS label, and date; version strings, body previews, and thumbnails are removed.
• Routine App Store updates are filtered from cross-product discovery surfaces (the "From other products" rail and the "Recent" ticker) unless the release carries an AI importance score of 4 or higher.
