Bump marketing/build versions for the Swift client, reuse the existing
App Store share-extension App ID, and add ExportOptions/fastlane/archive
scripts so the native binary can be signed and submitted without EAS iOS.
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.
