/**
 * AriaFlowRealtimeVoiceAgent — thin concrete class applying the
 * {@link withRealtimeVoice} mixin to {@link AriaFlowAgent}.
 *
 * Subclasses must either set `realtimeModel` to a constructed
 * {@link RealtimeAudioClient}, or override `createRealtimeModel(env)` so the
 * mixin can lazily build one (usually a `CloudflareGeminiLiveClient` with
 * `this.env.GEMINI_API_KEY`).
 *
 * @example
 * ```ts
 * import { CloudflareGeminiLiveClient } from "@ariaflowagents/realtime-audio";
 * import { AriaFlowRealtimeVoiceAgent } from "@ariaflowagents/cf-agent/voice";
 *
 * export class MyVoiceAgent extends AriaFlowRealtimeVoiceAgent<Env> {
 *   createRealtimeModel(env: Env) {
 *     return new CloudflareGeminiLiveClient({ apiKey: env.GEMINI_API_KEY });
 *   }
 *   protected getAgents() { return [{ id: "assistant", name: "Assistant", tools: {} }]; }
 *   protected getDefaultAgentId() { return "assistant"; }
 * }
 * ```

     * Hibernate between calls; stay awake during active calls via `keepAlive()`.
     *
     * Reasoning:
     *   - Client WS uses the agents-SDK `Connection` abstraction (hibernation-
     *     aware), so a reconnect after eviction lands on a rehydrated DO with
     *     `this.messages` + `this.state` restored from SQLite.
     *   - Outbound provider WS is not hibernation-aware, but `keepAlive()`
       *   is held for the duration of a call → no eviction during calls.
     *   - On `end_call` / teardown we close the outbound cleanly, then release
     *     keepAlive → DO can safely hibernate (free) between calls.
     *
     * Contrast: `cloudflare/agents/openai-sdk/call-my-agent` sets
     * `hibernate: false` because its `TwilioRealtimeTransportLayer` attaches
     * raw `.addEventListener` handlers bypassing the hibernation path — that
     * doesn't apply to us.
