 * install.mjs —— 把 fmode-code-lit 技能安装到 Claude Code 技能目录。
 *
 * 用法：
 *   node install.mjs install     # → ~/.claude/skills/fmode-code-lit/（全局，默认）
 *   node install.mjs workspace   # → ./.claude/skills/fmode-code-lit/（当前项目）
 *   node install.mjs install --target <dir> [--force]
 *   node install.mjs check       # 校验安装
