feat: 海外化改造（新加坡市场）—— 阶段 0-3

按 U-Claw-海外化改造方案.md 与 范围决策记录.md 实施。这是 fork，不回上游：
海外版删掉的正是上游的中国市场默认值。

阶段 0 地基
- 下载源全部改国际：脚本/CI 61 处 + lockfile 880 条 npmmirror URL 归零
  （lockfile 那 880 条是 npm 的 resolved 字段，脚本层参数化根本绕不过它）
- 移除 install.ps1 里三个第三方 GitHub 加速代理，bundle 改直连 + SHA256 校验
  （原来只检查"文件大于 1MB"就解压运行）
- 技能内容与分发分离：skills/manifest.json 单一来源，install.sh 1170→658 行、
  install.ps1 721→546 行，两者技能内容归零
  实测原来是三份不一致：skills-cn 完整、install.sh 约 40%、install.ps1 约 17%，
  且 7 个通用技能只有 U 盘版有 —— 一键安装的用户一个能用的技能都没有
- Node 版本三种（v22.14/16/22.1）统一，新建 NODE_VERSION 单一来源
- Config 页三份合一。portable/Config.html 用根相对路径调 API 却只从 file:// 打开，
  保存功能已静默失效两个月；现缩为 120 行重定向壳
- 测试接入 CI（此前 node --test 无人运行，所有断言形同虚设）

阶段 1 双语可用
- 浏览器侧 i18n：JSON 为源、生成经典 script（file:// 下 fetch 本地 JSON 被拦）
  语言跟盘走不跟机器走：启动器写 data/.openclaw/locale.js
- 8 处硬编码 lang="zh-CN" 归零，data-i18n 覆盖 213 处，词条 en/zh 各 279 条
- B3 单框 Key：12 张模型卡 → 一个输入框，前缀识别 provider，
  服务端 /api/test-key 发 1-token 请求实测，错误映射成人话
  Key 填错到得知：从"直到对话失败"降到 ≤1 秒
- 区域格式 SG：DD/MM/YYYY、12 小时、S$、Asia/Singapore
  （ICU 在 en-SG 下把 SGD 渲染成裸 $，与美元无法区分，故自行拼 S$）
- README 内容分叉而非翻译，§1.3 证据清单逐条清零

阶段 2 降门槛
- 启动逻辑上移 lib/start.mjs：Windows-Start.bat 220→28 行、
  Mac-Start.command 235→33 行
  修掉 Mac 侧两个 bug：控制台端口硬编码 18788（回落时打开死页）、
  微信插件从未在 Mac 上安装
- U 盘根目录 23 → 3 个可点文件，其余进 advanced/
- 首启向导：语言 → 用途（7 角色，manifest 驱动）→ 密钥，答过不再问
- 三档界面，Simple 档隐藏一切技术名词
- 自动自愈：启动失败先自查自修，修不好导出脱敏诊断包
  （Doctor 从"用户要知道去点的工具"变成后台机制）

阶段 3 技能库
- 19 个英文技能，planned 归零。sg-weather / sg-transport 的端点均实测过
- SkillHub 从 56 张手写第三方卡片改为 manifest 生成：703→125 行，中文归零

其他
- origin.json 收拢所有运行时地址，tests/origin.test.mjs 保证迁移不会漏
- portable/ 下用户可见中文归零（由断言保证）
- 82 项测试

未验证（本机无 Windows / 无 pwsh）：
- install.ps1、setup.ps1 约 210 行改动从未经 PowerShell 解析器
- 完整启动路径仅在假 node + 假 openclaw 上冒烟
- 8 个 .bat 的盘根推导仅静态断言
详见 U盘实测清单.md

受阻：
- 隐藏黑窗口 —— 需代码签名证书（.vbs 已被 Windows 弃用，替代方案都要签名）
- 场景卡 —— OpenClaw 上游 Dashboard 无预填 prompt 接口
- 官网 36 条 —— 上游 2026-04-14 拆到私有仓库，无权限
