docs(readme): update documentation to include mobile native support

- Add mobile native development capabilities to cross-platform features
- Include Android NDK and iOS SDK support in platform targets
- Update backend support to mention Android arm64-v8a and iPhoneOS arm64
- Add information about mobile app UI bridge architecture
- Include links to Android native app example and iOS/macOS native app example
- Clarify mobile development workflow with TypePHP for business logic
