refactor: 原型迁移 .superpowers/prototype → design/prototype（与 CONTRACT 同目录）

- git mv 全目录（历史保留）；.gitignore 收敛为整个 .superpowers/ 忽略
- 全仓 16 处引用同步（CI checks.yml / l1-sync / screens.mjs / hooks /
  CLAUDE.md / CONTRACT / SSR 模板注释 / docs / web 注释）
- 修 pre-commit 路径正则残留；5180 评审服务已切新路径
- 验证：check-ds 12 道 / l1-sync 6 道 / fidelity 抽查全过
