YAGPDB机器人星板自定义命令：嵌入消息音视频预览修复请求

原脚本存在的问题 #

• 链接正则中的&是HTML转义字符，而Discord消息中的链接使用原始&，导致带参数的媒体链接无法匹配
• 域名后缀长度限制过严（仅允许2-3位），无法匹配.dev、.app等新型域名下的媒体链接
• 路径匹配规则过于严格，无法匹配包含特殊字符的媒体路径
• 一处变量拼写错误（$eomji应为$emoji），导致高星数对应的表情显示异常

关键修复说明 #

1. 正则表达式优化：
   • 替换&为&，匹配原始链接中的参数分隔符
   • 将域名后缀长度从[\w]{2,3}改为[\w]{2,6}，支持更多新型顶级域名
   • 路径匹配改为(?:\/[^\s]*)*，匹配任意非空白字符组成的路径
   • 新增结尾的参数匹配(?:\?[\w=&%-]+)?，支持带查询参数的媒体链接
2. 变量拼写修复：修正了$eomji的拼写错误为$emoji，确保50星以下的表情显示正确
3. 附件遍历逻辑：从仅取第一个附件改为遍历所有附件，确保只要有符合条件的媒体附件就能被设置为Embed预览（Discord Embed仅支持一个主图，最后一个匹配的会生效）
4. 字段中文本地化：将Embed中的字段名改为中文，更符合国内用户使用习惯
