feat: 优化前端构建分发和模型价格更新机制

1. 前端构建分发优化：
   - 修改 GitHub Actions workflow，构建前端后推送到 web-dist 分支
   - 更新 manage.sh 安装脚本，从 web-dist 分支获取预构建文件
   - 解决部分机器无法本地编译前端的问题
   - 添加测试脚本 test-web-dist.sh 验证流程

2. 模型价格更新功能：
   - 添加手动更新模型价格脚本 update-model-pricing.js
   - 新增 npm run update:pricing 命令
   - 在 manage.sh 添加 update-pricing 命令和菜单选项
   - 支持备份、进度显示和统计信息

3. 其他改进：
   - 优化安装流程，减少对 Node.js 环境的依赖
   - 提供多种更新模型价格的方式
   - 改进错误处理和回退机制
