+/// Local, per-device inbox row overrides — mirrors desktop's
+/// `useFeedItemState`:
+/// - [doneIds] marks channel-less rows (e.g. approvals without an `h` tag)
+///   as read, since they have no NIP-RS context to advance.
+/// - [unreadIds] is the per-row "mark unread" override that reopens a row
+///   without rewinding the shared channel/thread read marker.
