feat(terminal): /en/terminal 双语薄壳——命令行为零分叉

- terminal.astro 抽 locale prop：frontmatter 静态文案 + script 层
  zh/en 双 DICT（命令描述/ls 路由表/whoami/exit 目标），双轨共享
  一份 chunk；路径守卫 Set{/terminal,/en/terminal}
- en/terminal.astro 四行薄壳 <TerminalPage locale="en" />
- Keyboard 帮助表 terminal 词条按 /en/ 前缀改写（其余表格文案
  双语化留给独立车道，注释已标）

车道：op-artalk（自验 15/15）；收编验收 build+双轨 playwright 过——
首验 FAIL 系验收方误用 textContent 吞了内联脚本中文注释，innerText
复核零中文，非车道缺陷

验证: pnpm astro build 30 页 exit 0（双产物）；双轨 playwright 验收
      （en 可见文案零中文/ls en 路由表/zh 回归/Keyboard 词条）全过

Spec: none (页型双语薄壳，车道级小活)
