fix(logic): 移除main.go中的多余空行 移除PprofWeb函数后的多余空行，保持代码整洁性 fix(fight): 修正effect_13.go中的效果应用对象 将效果应用从对方上下文改为正确的目标对象，修复技能效果逻辑 feat(middleware): 增强server.go中的自动化部署功能 - 添加下载链接格式校验，确保包含http/https协议 - 重构部署脚本，优化screen会话终止逻辑 - 改进下载过程，添加超时和重试机制 - 增强错误处理和日志输出 refactor(config): 更新server.go中的数据库查询方法 - 修改GetPort方法返回类型为gdb.List以提高兼容性 - 使用统一的DBM方法替代不同的数据库查询方式 ```
