Gemini Live ⇄ Firebase AI Logic Migration Skill

gemini_live has a compatibility layer, package:gemini_live/compat/firebase_ai.dart, that mirrors the Live API of firebase_ai 4.x: same class names, constructors, methods and defaults. Code written against it compiles on both packages after an import swap.
