+/**
+ * 将 Spirit 记录按 BelongGroupID 归类, 生成 group-X 父节点集合 + Layer 根直挂子节点.
+ *
+ * 规则:
+ *   - BelongGroupID === '0' (或缺失) → 直挂 Layer 根, 不进任何 group 父节点
+ *   - BelongGroupID > 0 → 归入对应 group-<N> 父节点
+ *   - group 父节点按 ID 升序排列; 同 group 内子节点按 IndexOfLayer 升序
+ *   - 命名保留原 BelongGroupID 值, 不重排
+ *
+ * 数据源权威: IndexOfLayer 缺失视作 0 (XML 中该字段由 readLayerXml 提供, 必有值).
+ *
+ * @param {Array<{ id?: string, group?: string, indexOfLayer?: string }>} spirits
+ * @returns {{ groupParents: Array<{ name: string, childSpiritIds: string[] }>, rootChildSpiritIds: string[] }}
