refactor(core): 拆分大型单体文件为模块化子组件

将三个超过 700 行的大型文件重构为模块化架构: Agent (1033 → ~400 行): - agent-tool-executor: 工具获取、过滤和执行 - agent-message-handler: 消息构建、流式处理 - agent-mode-manager: 模式切换和权限检查 - agent-vision-handler: 视觉处理委托 CheckpointManager (1015 → ~620 行): - checkpoint-store: 检查点 CRUD 操作 - checkpoint-rollback: 回滚和撤销操作 - checkpoint-session: 会话跟踪 - checkpoint-events: 事件发射系统 SessionManager (768 → 356 行): - message-converter: Part ↔ ModelMessage 转换 - session-store: 会话 CRUD 操作 - project-manager: 项目管理 - session-auto-save: 自动保存功能重构原则: 单一职责、编排器模式、向后兼容 API
