/**
 * `@audin.ai/operator-sdk` — headless browser SDK for the Audin operator
 * softphone.
 *
 * Make and receive phone calls from a browser over the Audin operator
 * WebSockets. No UI: you build the interface, the SDK handles the microphone,
 * audio transcoding, the signalling + media channels, reconnection and
 * heartbeats. Credentials stay on your backend — the SDK obtains short-lived
 * session tokens through the `getToken` callback you provide.
 *
 * @example
 * ```ts
 * import { AudinOperator } from "@audin.ai/operator-sdk";
 *
 * const op = new AudinOperator({
 *   coreUrl: "https://core.audin.ai",
 *   getToken: async () => {
 *     // Call YOUR backend, which holds the account key and proxies to
 *     // POST /operator-sessions/token. Return at least { token }.
 *     const r = await fetch("/api/operator/token", { method: "POST" });
 *     return r.json();
 *   },
 * });
 *
 * op.on("incomingCall", (call) => call.accept());
 * op.on("callStarted", (call) => console.log("on a call", call.callSid));
 * op.on("callEnded", (call) => console.log("ended:", call.endReason));
 *
 * const numbers = await op.listPhoneNumbers(); // [{ id, phoneNumber, displayName }]
 * const mine = numbers[0];
 * await op.goOnline([mine.id]);
 * const call = await op.dial("+39021234567", { callerId: mine.phoneNumber });
 * call.mute(true);
 * call.hangup();
 * await op.goOffline();
 * ```
