// 这是"一根可以写出任何工具链的笔". 不预装工具, 而在被调用时
// 现场合成工具:
//
// pen.write(intent) → 从能力字典 (capabilities) 组合, 落到 penned/{tool}/
// pen.list() → 列出已写出的工具
// pen.fetch(url) → 通过国内/海外双管道取外部资源
// pen.register(tool) → 把新工具注册进 manifest, 触发 PR
// pen.capabilities() → 列可用能力
//
// 作为 MCP server 监听 stdio (JSON-RPC), 也可以直接 require.
