+          - Add configureWeb() to allow bundling sql.js WASM locally (iOS, Android, web)
+          - Extract SQLConnection interface (src/sql-connection.ts)
+          - Add WebSQLConnection for web platform (src/web-sql-connection.ts)
+          - Move NativeSQLConnection to separate file (src/native-sql-connection.ts)
+          - Use native-platform check in FastSQL to dispatch between implementations
+          - Fix: add no-op configureWeb to Android and iOS native plugins
+          - Fix: replace @link tag with plain text in WebConfig JSDoc
+          - Update android/build.gradle sqlcipher version
