fix(workspace): 工作空间「查看」媒体文件直接播放(2026-09-18用户要求)——workspace_view.dspy原只渲染txt/md/json,视频/音频/图片全落'其他→下载查看'弹提示;补媒体分支:video_exts→VideoPlayer/audio_exts→AudioPlayer/image_exts→Image控件直接播放(三控件均已注册bricks.Factory,声明式widgetBuild可解析;workspace_file.dspy的FileResponse支持Range请求可拖进度);扩展名覆盖对齐workspace_open.dspy(编辑入口本就播放,查看入口补齐)
