 * install.mjs —— 把 fmode-code-agent 技能装到用户级/工作区级 .claude/skills/。

 * 用法：
 *   node install.mjs install [--force]     # 装到 ~/.claude/skills/fmode-code-agent/
 *   node install.mjs workspace [--force]   # 装到 ./.claude/skills/fmode-code-agent/
 *   node install.mjs rules [dir] [--force] # 等价于 install-rules.mjs
