feat(web): app shell — masthead, contents nav, theme toggle

Root layout now wraps every page in the editorial column with a masthead (wordmark + tagline + live worker dot) and a contents-bar nav with active state via usePathname. Theme toggle stamps data-theme on <html> and persists to localStorage. Pages no longer repeat the ad-hoc nav line. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
