Documentation and package page only: no API or behavior changes.

• The README opens with what the package does, a quick start (one widget, the hooks block, the doctor) and screenshots.
• The example's README (the Example tab) has the commands to run it and the code of the chat.
• A shorter description; the topics are llm, ai, chat, agents and on-device.
• pub.dev lists the platforms of the device plugin: Android, iOS and macOS (platforms:). The plugin still registers the native licenses on Linux and Windows.

Initial release.

• Chat UI in three tiers: LocalInferenceChat (one widget that makes, starts and disposes the model manager, the assistant and the model setup), ChatPage and ChatView over an AssistantController and a ModelSetupController kept above the Navigator (LocalInferenceScope), and headless Listenable adapters.
• Model setup UI: consent with the download size, progress with pause, resume and cancel, the mobile-data prompt, the model picker and ModelLibrary.
• Customization: LocalInferenceTheme (a ThemeExtension), LocalInferenceStrings (Italian and English, with LocalInferenceLocalizations.delegate), ChatFeatures, ChatBuilders and ModelSetupBuilders (each builder can wrap the default widget), ChatCallbacks and LocalInferenceKeys.
• Compliance and accessibility: an AI disclosure, reply reports, an AI-generated semantics hint, live regions, screen-reader announcements, 48-point targets, text scaled up to 2.0 and right-to-left layout.
• Background model download on background_downloader (BackgroundModelDownloader): downloads that go on while the app is in the background, Wi-Fi only or on mobile data, resume after a failure or a relaunch (RetainingResumeStorage), the content checked before a download counts, and notifications in Italian or English.
• LocalInferenceFlutter: installDownloaderStorage, createModelManager, createAssistantController, platformDefaults, platformLoadOptions and checkDeviceSupport.
• A device plugin for iOS, macOS and Android: memory, free disk, a native SHA-256, the backup exclusion, the no-backup folder, the network type and a diagnostics snapshot (thermal state, battery, memory).
• LifecyclePolicy: what a running turn and the model do when the app leaves the foreground.
• The licenses of the bundled native libraries on the app's license page, registered before main() with no app code (NativeLicenses).
• package:local_inference_flutter/testing.dart re-exports local_inference's test doubles. dart run local_inference_flutter:doctor runs the host doctor; --install-ios-script adds the build-phase script that fixes ITMS-90208 for the llama.cpp framework.
• Flutter 3.44 or newer. iOS 16.4, macOS 14.0, Android minSdk 24 with API 28, arm64-v8a and a 64-bit process checked at run time (not run on an Android device yet). Linux and Windows get the license notices only.
