v4.7.0

• Native SDKs 4.7.0 on both platforms.
• iOS: document and face auto-capture now run on a leaner TFLite engine instead of MediaPipe - about 12 MB smaller to download and roughly 8.5 MB smaller inside the app, detection behavior verified frame-for-frame identical on a physical-device matrix before release, and document inference about 40% faster.
• iOS: auto-capture inference degrades gracefully through a runtime retry ladder; total engine failure still falls back to manual capture, never a crash.
• Android: the native SDK gained an optional didit-sdk-autodetection-play artifact that runs auto-capture on the Google Play services ML runtime (~43 MB smaller universal APK). This package's diditSdkAndroidVariant options are unchanged in this release; wrapper-level opt-in support is planned as a follow-up.
• Both platforms: new session diagnostics (engine selection and inference latency) help support teams pinpoint device-specific capture issues.
