Performance: Framer-motion aus kritischem Pfad entfernt

- Framer-motion aus Layout, NavLink, ContactInfo, LanguageSwitcher entfernt
- PageTransition komplett vereinfacht (keine 1200ms Verzögerung mehr)
- FloatingPaths wird erst nach 2s lazy geladen
- Framer-motion und lucide-react in separate Chunks getrennt
- Icons-Chunk: 10.87KB (statt 126KB ui-vendor)
- Animations-Chunk wird erst bei Bedarf geladen

Einsparung: ~115KB beim Initial Load
