Generate styled placeholder covers (title, author, book icon) when a book has no embedded cover image, instead of showing a blank rectangle. - Add PlaceholderCoverGenerator lib with 1-bit BMP rendering, scaled fonts, word-wrap, and a book icon bitmap - Integrate as fallback in Epub/Xtc/Txt reader activities and SleepActivity after format-specific cover generation fails - Add fallback in HomeActivity::loadRecentCovers() so the home screen also shows placeholder thumbnails when cache is cleared - Add Txt::getThumbBmpPath() for TXT thumbnail support - Add helper scripts for icon and layout preview generation Co-authored-by: Cursor <cursoragent@cursor.com>
