直播弹幕与界面优化

- useLiveDanmaku: 重写协议解析，支持 zlib 压缩消息、token 认证、base64 帧处理
- services/bilibili: 新增 getLiveDanmakuInfo 获取弹幕服务器信息
- live/[roomId]: 使用真实 roomid 而非 URL 别名连接弹幕
- NativeVideoPlayer: 增加中文注释，移除调试日志
- video/[bvid]: UP主头像移至标题前，调整字号与样式
- index: 替换 logo 文字为下载按钮图标
- videoRows: 修复奇数视频配对，调整 BigRow 位置策略
- package.json: 移除未使用的 fast-xml-parser 和 xml2js 依赖
