chore: 发布脚本 — 全平台构建打包 + gitcode release 资产上传

- scripts/release.sh: 前端构建 → 6 平台交叉编译 (linux/windows/darwin ×
  amd64/arm64) → tar.gz/zip 打包 → SHA256SUMS；子目录隔离同名二进制
- scripts/upload_assets.py: gitcode 两步上传流程
  (upload_url 签名 → urllib PUT 到 OBS)，curl 会 401 但 urllib 干净成功
- 首次发布 v0.1.0: 6 个平台安装包 + SHA256SUMS 已上传，下载校验一致

+"""上传 release 资产到 gitcode（两步：取签名 URL → PUT 到 OBS）。

+用法: upload_assets.py <version> <token> [file...]
+不传 file 时上传该版本目录下所有 tar.gz/zip 与 SHA256SUMS。
