# 全量代码门禁：部署前在本地开发机执行，确保后端 + 前端检查全绿。
#
# 用途：
#   - 部署门禁：scripts/deploy-prod.sh 在 build 镜像前自动调用本脚本（--skip-check 可跳过）
#   - 手动校验：开发时手动跑 ./scripts/check.sh
#
# 包含：
#   数据库：SQL 约束与迁移完整性检查
#   后端：go vet + go build + go test
#   前端：npm run check (prettier + eslint + typecheck) + npm run test + npm run build
#
# 任一步骤失败即退出非零，阻止部署。
