Replace Flutter app with native SwiftUI rewrite (iOS 26)
Complete ground-up rewrite in SwiftUI targeting iOS 26. Drops the Flutter/Dart codebase entirely in favour of a lean native app with no third-party dependencies. Features shipped: - Bookmark list with pagination, pull-to-refresh, swipe delete/archive - Add bookmark form + iOS share extension (zero-tap save from any app) - Tags tab — all tags sorted by count, tap to browse filtered bookmarks - Native search tab (Tab role: .search) with instant client-side filtering - AI enrichment via OpenRouter (google/gemini-2.0-flash-lite-001): auto-summary and tag generation, semantic search, smart collections - Settings: linkding server config, OpenRouter API key - App Groups for credential sharing between main app and share extension - Swift 6 strict concurrency throughout (@Observable, @MainActor) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
