- 将 AbstractLogger 实现从 ILogger 扩展为 IStructuredLogger 接口 - 添加通用日志方法 Log(LogLevel, string, params object[]) 支持格式化参数 - 实现结构化日志方法支持属性键值对记录 - 添加 ConsoleAppender、FileAppender 和 AsyncLogAppender 日志输出器 - 实现 CompositeFilter 过滤器和 DefaultLogFormatter、JsonLogFormatter 格式化器 - 在 ConsoleLogger 和 GodotLogger 中使用预缓存的日志级别字符串提升性能 - 使用 ANSI 颜色代码替代 ConsoleColor 实现跨平台日志着色 - 在 ConsoleLoggerFactoryProvider 和 GodotLoggerFactoryProvider 中添加日志工厂缓存 - 优化 FileStorage 中目录遍历使用 OfType<string>() 类型转换 - 添加 LogContext 支持异步流中的结构化属性传递
