Add dark design system with CSS custom properties and refined typography

Establish a cohesive dark UI foundation: - Define CSS custom properties for surfaces (4-level depth hierarchy), borders, foreground text (3-tier), accent colors, and canvas background - Add Inter (text) and JetBrains Mono (code) font loading via Google Fonts - Extend Tailwind with semantic color tokens, typography scale (caption/body/ subheading/heading), box shadows (card, glow), and animations (fade-in, slide-in, skeleton shimmer) - Add component-layer utilities: .btn system (primary/secondary/ghost/danger), .glass frosted overlays, .custom-checkbox, .skeleton loaders - Add .prose-message typographic styles for rendered markdown content - Add search minimap CSS (tick marks, viewport indicator) - Restyle scrollbars for thin dark appearance (WebKit + Firefox) - Replace hardcoded Tailwind color classes in CATEGORY_COLORS with semantic tokens (dot/border/text) mapped to the new design system Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
