Replace the abandoned RN iOS path with a SwiftUI app (iOS 17+) that reuses the shared TipTap editor bundle, GRDB local mirror/outbox, and Android-aligned shell chrome for list, create, detail, and Me. Package the editor HTML in the app resources so Markdown renders, present edit from the workspace root with a UIKit FAB, and keep caret stable while typing.
