🎨 feat(web/default): add Anthropic theme preset and configurable serif typography

Introduce a switchable Anthropic-inspired color preset and a new Font customization axis so users can adopt the editorial serif look across the entire UI, including sidebar navigation, tabs, form controls, buttons, and table headers. Theme preset Add anthropic to the theme preset registry with warm cream canvas, slate foreground, and clay/coral accent tokens for light and dark modes Define explicit surface colors for the Anthropic preset instead of relying on the semantic surface bridge Exclude anthropic from the primary-color surface bridge so bespoke warm neutrals are not overridden by accent-tinted mixes Typography system Add @fontsource-variable/lora and a global --font-serif token with CJK serif fallbacks (Noto Serif SC, Source Han Serif, Songti SC, etc.) Introduce a --font-body token and drive <body> font-family from it Add a Font axis (default | sans | serif) parallel to radius/scale Resolve font: 'default' against preset defaults (anthropic → serif) Persist font preference via cookie and apply data-theme-font on <body> Apply serif OpenType features (kern, liga, calt, tnum) and heading display tuning when serif is active Remove per-component sans opt-outs so serif inherits through sidebar, tabs, inputs, buttons, badges, and table headers via natural CSS cascade Keep monospace contexts unchanged via Tailwind preflight and .font-mono UI and i18n Add Font selector to the theme config drawer (Auto / Sans / Serif) Add "Font" and "Select body font" translations for en, zh, fr, ja, ru, vi Misc Tighten group and status badge sizing for better balance with serif text
