Both StoryDetailView and ArticleReaderView now show three icon buttons in
the navigation bar trailing area:
- Share (square.and.arrow.up) — story headline+summary+URL / article
headline+sourceUrl, passed to UIActivityViewController via ShareSheet.
- Save (bookmark / bookmark.fill, orange when active) — toggles SavedStory
in SwiftData; StoryDetailView also ensures a CachedStory exists so the
Saved tab can display it offline.
- Mark read/unread (checkmark.circle / checkmark.circle.fill, orange when
read) — toggle mirroring the swipe action already present in the feed.
The read state in StoryDetailView is still auto-marked on open (.task
→ markRead()); the toolbar button lets users undo that without going back
to the feed. ArticleReaderView targets the parent story (route.storyId).
