 - 新增 `ReduceAuditViewPlugin`（`ReduceAuditViewPluginKey`）用于替换减签人员选择视图；默认实现为占位，集成方应列出当前节点的待审批人（不含当前审批人）。
 - 设计器新增减签动作配置：仅「减签人员范围」（script），不提供「最大可选人数」。
 - `FlowMessageKey.APPROVAL_REDUCE_AUDIT` 增加默认提示文案。

+- 合并审批（记录合并）必须先勾选要处理的流程记录才能提交，取消勾选会同步清空选择；此前表单有数据即可绕过校验，导致未选择流程也能通过/拒绝/保存/转办。
+- 设计器「相同人员提交配置」未配置时默认展示「手动审批」，与后端未配置时的实际行为一致（issue #224 已移除默认策略，不再显示空值）。
