AiChatView class
A batteries-included chat surface: the AiChat transcript above an
AiPromptInput, laid out and safe-area-aware. Drop it straight into a
Scaffold body — the fastest path from pub add to a working chat:
Scaffold(body: AiChatView(controller: controller));
Everything is overridable; reach for AiChat + AiPromptInput directly only when you need a custom layout between them.
