/**
 * [WHO]: SessionSettingsAccessors() mixin — AgentSession 的 settings getter/setter 转发面
 * [FROM]: Depends on SettingsManager type and a minimal host interface
 * [TO]: Consumed by AgentSession (core/runtime/agent-session.ts) via mixin composition
 * [HERE]: core/runtime/session-settings-accessors.ts — settings accessor surface of AgentSession
 *
 * 拆分背景：agent-session.ts 曾有 115 个方法，其中 52 个是 settingsManager 的
 * 一行转发（display/model/image/behavior settings 的 GUI-facing 访问面）。
 * 这些方法不含会话逻辑，抽离后主类瘦身 ~300 行，公共 API 面不变
 * （mixin 方法落在原型链上，session.getTheme() 等调用方无感知）。
