# =============================================================================
# PR Preview: Build — 构建所有预览产物
#
# 触发时机: PR 打开 / 有新推送 / 重开时自动运行
# 功能:
#   1. playground 构建 — 用于 surge.sh 在线预览（所有 PR 均触发）
#   2. Client 全平台构建 — packages/cherry-markdown 或 packages/client 变更时触发
#   3. VSCode Plugin 打包 — packages/cherry-markdown 或 packages/vscodePlugin 变更时触发
# 所有构建产物上传为 artifact，由 pr-preview-deploy 统一处理
# 注意: Client 和 VSCode Plugin 构建失败不影响主流程 (continue-on-error)
# 并发控制: 连续提交取消旧运行
