+/**
+ * 读取 Game_Surface_3 风格的 Layer XML (UTF-8 编码), 解析 Layer + Spirit 字段.
+ *
+ * 协议来源: docs/protocol/ (服务器零改动). XML 结构与 save/Layer*.xml 一致:
+ *   <Layer>
+ *     <PropertyList><Property Name="ID" Value="2"/><Property Name="Name" Value="..."/></PropertyList>
+ *     <SpiritList>
+ *       <Spirit>
+ *         <PropertyList><Property Name="SpiritType" Value="0"/>...</PropertyList>
+ *       </Spirit>
+ *     </SpiritList>
+ *   </Layer>
+ *
+ * 数据源权威: 字段缺失/不存在一律返回 undefined (不上游兜底, 由下游显式判错).
+ *
+ * @param {string} path - 文件路径 (相对 cwd 或绝对)
+ * @returns {{ layerId: string|undefined, layerName: string|undefined, spirits: Array<{ id, name, type, imgResID, x, y, w, h, group, indexOfLayer }> }}
