fix: SEO canonical URLs, LCP performance, remove unused dependencies

- Remove duplicate app/projects/ route (was causing 5xx and soft 404) - Fix nginx: redirect www.dk0.dev → dk0.dev (non-www canonical) - Fix not-found.tsx: locale-prefixed links, remove framer-motion dependency - Add fetchPriority='high' and will-change to Hero LCP image - Add preconnect hints for hardcover.app and cms.dk0.dev - Reduce background blur from 100px to 80px (LCP rendering delay) - Remove boneyard-js (~20 KiB), replace with custom Skeleton component - Remove react-icons (~10 KiB), replace with inline SVGs - Conditionally render mobile menu (saves ~20 DOM nodes) - Add /books to sitemap - Optimize image config with explicit deviceSizes/imageSizes
