feat(LogManager): 新增日志持久化功能

- 新增 LogManager 单例类,支持日志文件按日期滚动
- 创建 CallerInfoFormatter 自定义格式化器，提取真实调用位置
- 为 MsgBase._showTrace 方法添加日志级别参数，集成日志系统
- 新增 initializeLogManager 初始化函数,日志存储于 AppDataLocation/logs/
- 日志输出格式对齐:[时间] - [类名(15)|级别(8)] - [文件：行号(20:4)] - 消息
- 控制台/INFO级别,全量日志 / DEBUG 级别，错误日志 / ERROR级别
- 全量日志保留7天,错误日志保留14天
