    Class DocumentMessageRouter

    Document message router service. Provides centralized message routing with handler registration pattern. Eliminates code duplication between NotebookProvider and LexicalProvider.

    const router = new DocumentMessageRouter(logger);
    await router.initialize();

    // Register handlers
    router.registerHandler('select-runtime', async (msg, ctx) => {
      // Handle runtime selection
    });

    // Route message
    await router.routeMessage(message, context);
