/**
 * LiveKit Agents agent definition — realtime (Gemini Live speech-to-speech).

 * `defineRealtimeVoiceAgent` returns the agent object placed as the default
 * export of a worker entry file. Unlike the cascaded `defineVoiceAgent`
 * (Silero VAD → STT → NeuroLink → TTS), here a single realtime model (Gemini
 * Live on Vertex) does STT + reasoning + TTS + turn detection over one
 *
 * `@livekit/agents`, `@livekit/agents-plugin-google`, `@livekit/rtc-node`, and
 * `@google/genai` are imported dynamically so the core package does not require
 * them unless the realtime agent is used. Type-only imports are erased at build.
