Book Sources overhaul
• Browse aggregated public catalogs (Project Gutenberg, Wenyuange, The Anarchist Library, Elephant Archives, arXiv, and more) as soon as you open the tab—no need to toggle built-in sources first
• Category filters with a preview row plus an All menu for faster discovery
• Local cache with background refresh so returning feels instant while new results update quietly
• Infinite scroll to load more titles
• Better covers: proxied/cached art when available; clearer generated covers when a source has none
• Custom OPDS catalogs still supported; Audiobooks and Point-Read tabs unchanged
• Sticky header (categories + search) while only the book list scrolls
