feat: redesign entire portfolio with bold modern dark theme

Complete visual overhaul of all pages and components with generous spacing,
bold typography, hover effects, gradient accents, and section differentiation.
Hero features animated terminal mockup and gradient text. Cards use hover
transforms with brand-colored shadows. CTAs use gradient backgrounds.
All i18n keys, data structures, SEO meta, and composable logic preserved.
