/**
 * [WHO]: Provides exportSessionHtml(), getLastAssistantText()
 * [FROM]: Depends on agent-core/ai public message types, export-html, ExtensionRunner, SessionManager, Theme
 * [TO]: Consumed by core/runtime/agent-session.ts facade methods
 * [HERE]: core/runtime/export-bridge.ts - HTML export bridge extracted from AgentSession
 *
 * Extracted from AgentSession (P4.6). This module owns HTML export wiring and last-assistant
 * text extraction. AgentSession remains the public facade and injects the optional Theme.
