# Beta 分支自动构建流水线
#
# 触发：push 到 beta 分支 / PR 到 beta / 手动触发。
# 产出：
#   1. 前端 + 后端编译验证（go vet / go test / go build）
#   2. 多平台可执行二进制 artifact（linux/amd64、linux/arm64、windows/amd64）
#   3. ghcr.io/{owner}/mebox:beta 多架构 Docker 镜像（linux/amd64 + linux/arm64）
#
# 与 main 分支的发布流（Auto-docker-publish.yml）隔离：beta 不做版本递增、
# 不打 release tag，只构建带 -beta 标识的产物供测试。
