feat: add dark/light theme toggle with system preference support (#18)

Add theme switching with three modes (system/light/dark) using Tailwind v4
class-based dark mode. Theme preference is persisted in localStorage and
defaults to the system's prefers-color-scheme. All components updated with
dark: variants for consistent dark mode rendering including SVG elements.
