feat: 播放页按来源列表切换,新增作者/搜索/hashtag 侧栏
- 播放上下文:作品链接带上来源(搜索、标签、作者、hashtag),上一条/下一条 在该列表内移动;当前作品不在列表中时退回全部作品的发布时间顺序 - 顶部提示标签显示当前列表与位置,点击打开侧栏列表,✕ 退出 - 侧栏改为「评论 | TA的作品 | 搜索结果/#hashtag」标签页,作品封面网格可就地切换 - 作者模式:打开「TA的作品」进入,关闭侧栏不退出,点提示 ✕ 后回到原来的列表 - 从搜索结果进入或点 hashtag 时自动打开对应列表 - 描述中的 hashtag 可点击,按完整 hashtag 精确匹配(#丰川祥子 不含 #丰川祥子cos) - 新增 /api/playlist;搜索 SQL 抽到 lib/search-query.ts 与播放页共用,保证顺序一致 - 移动端:底部抽屉、点作品后收起,媒体区支持上下滑切换 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
