feat: add Paper Routes and package five design systems

Add the paper direction with thin tracks, outlined hexagons and line arrows, without exterior color markers or piece numbers. Add a unified catalog for five designs and their 25 themes, with direct review links.

Organize each design into an authored design.md, generated tokens.json and preview. Add Agent routing, shared integration guidance, a machine-readable manifest and an executable rendering example. Preserve legacy preview and document links.

Validation: 16 focused design, theme and package tests passed; npm run design and static build passed. Confirmed all eight authored documents survive generation unchanged. Browser checks covered mobile, tablet and desktop layouts, theme links and migrated previews. Native engine integration and visual verification remain pending.

-## 游戏道具与布局
-
-- 撤销、重来、提示使用独立彩色底座，64–68px，图标 32px，标签 13px。顶部导航保持紧凑。道具使用纯色平面，不使用阴影、立体底边或渐变高光。
-- 右上角预留次数或“▶ AD”角标。设计稿展示“撤销 3 次”和“广告获取提示”，仅为样式，不启用真实库存或广告逻辑。
-- 棋盘在通知区与独立旋转区之间垂直居中。旋转区和道具区占据真实布局行，不覆盖棋盘。
-
-此方案使用独立的棋子造型、轨道材质和控件样式，共用现有弯曲轨道玩法。审核页支持同时保留多套方案。
