feat: make docs theme-aware using CSS variables

- Update Tailwind config to use CSS variables instead of hardcoded colors
- Colors now reference theme variables: var(--text-primary), var(--text-secondary), etc.
- Fix Tokyo Night theme: text-secondary corrected from #565f89 to #9aa5ce
- Typography plugin now uses var() for theme-aware prose styling
- Enables docs to respect theme system like rest of app
