Restore Codegen imports and public types for React Native 0.78 while keeping compatibility with the Strict TypeScript API in newer versions. Add a regression test and regenerate the published artifacts.

Update the development environment and example app to React Native 0.88.1 and React 19.3.1, including Jest, Android build configuration, and the iOS SceneDelegate lifecycle. The library's React 19+ and React Native 0.78+ requirements remain unchanged.

Prepare version 1.1.1, update the changelog, and align the CocoaPods source tag with v{version}.

Validation:

• 101 Jest tests, TypeScript, lint, and package build pass.
• The packed library passes consumer type checks and Babel transforms under RN 0.78 and 0.88.
• Release builds pass on iOS and Android with RN 0.88. Loading/content toggles, multiline skeletons, and Fade/Shrink/Collapse transitions pass on both platforms; Reduce Motion passes on Android.
• An independent Android RN 0.78 app builds in Release from the tarball and passes runtime checks for GleamView.Line and onTransitionEnd.

Full iOS RN 0.78 build validation is limited by an upstream fmt 11.0.2 compilation failure with Xcode 27.2. The same error reproduces when building fmt alone without Gleam.
