Make the shared TipTap link mark non-inclusive so text typed after a pasted or terminal link remains plain across web, desktop, Android, and iOS editors.
Refs #355
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.
