Subject: [PATCH] ui: light theme default + dark/light toggle

- Light theme: clean white (#fff) base, soft gray surfaces, professional feel
- Dark theme: deep navy (#0f1117), elevated layers, subtle shadows
- Theme toggle button (moon/sun icons) in header, persists via localStorage
- Auto-detects system prefers-color-scheme on first visit
- CSS variables for all colors, both themes defined in same file
- Improved contrast ratios for both modes (WCAG AA)
