feat: card/list view toggle for Reader with thumbnails

- Card view: large thumbnail from article content, feed name, title, author, reading time
- List view: compact rows with mini thumbnail on right
- Toggle button in toolbar (grid/list icon)
- Thumbnail extracted from first <img> in article HTML
- Card view is default, warm Atelier styling preserved
