/**
 * Chat Widget — thin re-export shim.
 *
 * The entire chat implementation moved to a layered architecture as part of
 * the May 2026 Preact rewrite. The previous monolithic ~3800-line class
 * (`LazyLoadedChat`) is now decomposed into:
 *
 *   - controller/  (chat-controller, ably-client, ably-handlers, ably-token,
 *                   message-stream) — orchestration and Ably transport
 *   - store/       (chat-store)     — signal-based reactive state
 *   - ui/          (ChatRoot.tsx + components + hooks)
 *                                   — Preact components rendered in a Shadow DOM
 *   - widgets/     (collect-email.tsx, escalate-to-human.tsx)
 *                                   — built-in tool widgets (Preact)
 *
 * See `docs/modules/chat/widget-architecture.md` for the full architecture.
 *
 * This file remains so external callers (`entrypoints/chat.ts`,
 * `ChatWrapper`, tests) can keep importing `LazyLoadedChat` from
 * `extensions/chat/chat` unchanged. New code should import the controller
 * and store directly from their own modules.
