Replace the per-turn POST /tasks approach for voice calls with a
long-lived agent run loop tied to the call lifecycle:
agent-service:
- Add AsyncQueue<T> utility for blocking message relay
- Add VoiceSessionManager: spawns one background run loop per voice call,
accepts injected messages, terminates cleanly on hangup
- Add VoiceSessionController with 3 endpoints:
POST /api/v1/agent/sessions/voice/start (call start)
POST /api/v1/agent/sessions/:id/voice/inject (each speech turn)
DELETE /api/v1/agent/sessions/:id/voice (user hung up)
- Register VoiceSessionManager + VoiceSessionController in agent.module.ts
voice-agent:
- AgentServiceLLM: add start_voice_session(), terminate_voice_session(),
inject_text_message() (voice/inject-aware), _do_inject_voice()
- AgentServiceLLMStream._run(): use voice/inject path when voice session
is active; fall back to per-task POST for text-chat / non-SDK engines
- entrypoint(): call start_voice_session() after session.start();
register _on_room_disconnect that calls terminate_voice_session()
so the agent is always killed when the user hangs up
