Usage: bash scripts/qa/run-business-flow-gates.sh <local|attached|list>

说明：
  local     通过 scripts/qa/run-web-gates.sh business-flow-local 准备临时库和服务后运行
  attached 复用当前 E2E_BASE_URL 直接按业务域执行 Playwright
  list      仅输出业务域与用例清单

可选环境变量：
  BUSINESS_FLOW_GROUPS=auth,reimbursement  仅运行部分业务域
  BUSINESS_FLOW_EXCLUDE_SPECS=tests/e2e/a.spec.ts,tests/e2e/b.spec.ts
                                           从已选业务域中排除指定 Playwright spec，多个值可用逗号或空白分隔
  E2E_BASE_URL                             attached 模式下必填或沿用 Playwright 默认
