feat: 优化GUI用户体验和打包配置

主要改进：
1. GUI界面优化
   - 自定义文件上传显示组件，替换默认列表为更美观的卡片式展示
   - 支持环境变量 PROJECT_TEMP_DIR 配置临时目录路径
   - 优化文件导出路径管理，统一使用临时目录
   - 改进端口查找逻辑，从8082开始避免常用端口冲突
   - 修复打包后无控制台模式的stdout/stderr处理

2. 打包配置改进
   - 更新Makefile使用.spec文件进行打包
   - 添加nicegui-pack打包选项
   - 优化clean命令，使用Python跨平台清理

3. 代码优化
   - 注释掉main.py中的详细统计信息打印
   - 改进打包环境的日志配置方式
