ci: release upload 改用 Gitea API 直调

softprops/action-gh-release@v2 在 Gitea 上偶发不工作, 改用
Gitea 原生 API:
  POST /repos/{owner}/{repo}/releases   <- 创建 release
  POST /repos/{owner}/{repo}/releases/{id}/assets  <- 上传 binary

token 走 secrets.GITHUB_TOKEN (Gitea 自动注入平台 token),
api_url 走 \${{ github.api_url }} (Gitea 自动解析).

RELEASE_ID 从 POST /releases 响应 grep 出来 (用 -oP "id":\s*\K[0-9]+).
- PCRE 模式 (grep -P) 依赖 GNU grep, ubuntu 镜像自带有, alpine
  runner 需要补 pcre 工具. 跟之前去 jq 一样是 runner 镜像依赖,
  这次保留因为已经在用 \${{ secrets.GITHUB_TOKEN }} 这种 GitHub
  风格 secret, runner 假定 ubuntu-family.

asset 上传字段是 attachment (Gitea API 文档要求, 不是 name).
