# 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 多架构 Docker 镜像（linux/amd64 + linux/arm64），
#      标签：beta（滚动）+ {基版本}-beta.{短 SHA}（本次构建，只增不改）
#
# 与 main 分支发布流（Auto-docker-publish.yml）的关系：镜像的构建方式、标签策略
# 和基版本号来源（version 分支）与发布流保持一致，区别是 beta 不做版本递增、
# 不打 release tag、不发布 GitHub Release、不部署服务器。
