feat: iOS Reader tab — full RSS reader with article reading pane

New third tab in the iOS app with:
- ReaderModels matching Reader API response shapes
- ReaderAPI with all endpoints (entries, feeds, categories, counters)
- ReaderViewModel with filters (Unread/Starred/All), pagination, feed management
- ReaderTabView with sub-tabs and feed filter chips
- EntryListView with infinite scroll, context menus, read/unread state
- ArticleView with WKWebView HTML rendering, star/read toggles, Save to Brain
- ArticleWebView (UIViewRepresentable WKWebView wrapper)
- FeedManagementSheet with add/delete/refresh feeds, categories
- Warm Atelier design consistent with existing app
