name: Docker Build and Push

# 仅 main 分支 push 触发 (每次提交 → 自动部署)
# 每次主分支提交: 构建前端 + 生成 OTA 升级包 (minisign 签名) → 打进 Docker 镜像 → 部署到 :3002
# OTA 随镜像发布: 容器内 OTA_PACKAGE_DIR=/app/ota-package 指向打包的 ota-package/
# 依赖配置注册中心 (bh.vps.honor3.com:8008):
#   - service-wardrobe / ota : MINISIGN_PRIVATE_KEY (整段 .key 内容, 多行)
