fix: Twitter bird CLI fetch failed — 自动代理注入 + 连通性检测 + Exa fallback
问题:bird CLI 用 Node.js 原生 fetch(),不走 HTTP_PROXY, 导致需要代理的用户(如 Windows + 本地代理)完全无法使用。 修复: 1. 自动代理注入:检测到 HTTP_PROXY/HTTPS_PROXY 时,通过 undici 的 EnvHttpProxyAgent 让 Node.js fetch 自动走代理,用户无需任何额外配置 2. doctor 检测:实际跑 bird whoami 测连通性,失败时给出具体原因 3. search fallback:bird 搜索失败时自动 fallback 到 Exa 4. install:自动安装 undici(npm install -g undici) 5. 新增 troubleshooting.md:常见问题解决方案 Fixes #9
