Capacitor LocalStorage Migration

Capacitor plugin (v1.2.0) to migrate legacy localStorage data from UIWebView (iOS) and Crosswalk WebView (Android) to modern Capacitor WebViews. Supports both Crosswalk SQLite and system WebView LevelDB formats. Preserves original database files for safety and allows retry. Peer dep on @capacitor/core >=7.0.0. Ships TypeScript types. Released ~2023, no active development observed. Key differentiator: handles both SQLite and LevelDB, uses hidden WebView for reliable LevelDB access.
