refactor(agent): 将 Summary Model 改造为内置 Sub Agent

- 扩展 AgentMode 类型添加 'internal' 模式
- 新增 summary agent preset (claude-3-5-haiku)
- AgentRegistry 添加 getInternal/listInternalAgents 方法
- CompressionManager 添加 setSummaryModelFromAgentConfig
- Agent 构造函数改用 Registry 配置初始化 Summary 模型
- 清理旧的 SummaryConfig 配置系统
- UI AgentsPanel 分离显示 System/Preset/Custom agents
- UI AgentEditor 为 internal agent 显示简化编辑界面
