fix: F2 映射改为纯 PathId（段序列直查，删除全部名字/链匹配）
根因（经导出代码 + 固定文件树对比验证）： - 导出 = document.ExportToNwd(ExcludeHiddenItems=true)（临时隐藏 itemsToHide） - 导出树段序列 = 主模型树跳过 itemsToHide 的可见子编号（模拟 vs 副实例实际树完全一致） - 此前链（名字）匹配在重名模型（Revit 嵌套实例）中映射到错误实例， 导致聚焦错误对象触发 NW 原生视角崩溃 修复： - 导出时 BuildSegmentMap：全树深度优先遍历，跳过 itemsToHide， 段序列 → 主 PathId（CreatePathId）映射（2112 条） - 副实例碰撞对象 PathId（段序列）直查表 → 主 PathId/ModelIndex - 删除 TryMatchChainTail/链尾部匹配/名字候选等全部名字相关代码 （TrimRootFromChain/BuildAncestorChain 保留——移动物体副实例解析用） 验证：Factory 实测映射 1/1、4/4（纯 PathId，无名字）；集成测试 25/25
