' NX Journal: 按需生成服务 worker (二期 A 版, NX 2506 实测适配版, 2026-08-27)
'
' ▍干什么: 常驻轮询 GenServer 任务队列, 认领任务后在**同一 NX 会话内**逐项生成:
'   开母模副本 → 设表达式 → 更新 → Save 副本 → PRT SaveAs →
'   CloseAll 释放句柄 → 外部独立翻译器导出 STEP/IGES → 关闭不保存。
'   结果写 jobs\job_<id>.done (行式键值格式, 无 JSON — NX journal 编译环境没有 JSON 库)。
'
' ▍关键改造 (2026-08-27): 批处理内 DexManager 导出判 0 solid (ST-DEVELOPER 翻译器
'   在 run_journal 无 GUI 下读不到几何), 改为 Save 副本后 spawn 独立命令行翻译器
'   step214ug.exe (.prt→.step) / iges.exe (.prt→.igs), 实测成功。
'
' ▍任务文件格式 (GenServer 写入, 本脚本解析; 母模/映射/开关/导出配置全部烘进任务, 不读 masters.json):
'   ITEM
'   SERIES=KC
'   CODE=KC0032-87
'   PARAM type=00            (每参数一行, 值可为空)
'   PARAM bore=32
'   MASTER=KC_master.prt
'   MAP bore=bore            (目录参数代码=NX表达式名)
'   SW magnet,=magOn,0       (参数代码,参数值=NX表达式名,表达式值)
'   EXP step=1               (导出格式开关; step 恒 1)
'   END
'
' ▍运行 (run_journal 只接受一个参数; 用 WorkingDirectory 定位配置):
'   WorkingDirectory = GenServer 运行目录 (含 worker-config.txt + worker-no.txt)
'   run_journal.exe <本文件完整路径>
'
' ▍注意
'   - 中文注释需 UTF-8 带 BOM (改完手动恢复 BOM)
'   - 母模副本现在必须 Save (独立翻译器从磁盘读); 但副本用完即删, 绝不保留脏副本
'   - 导出格式 (masters.json exports): step 恒导出, iges/prt 可选, parasolid/stl 已按用户要求砍掉
'   - NX 2506 关键 API (反射探针核对): OpenBaseDisplay(批处理必须, OpenBase 后 Work=NULL) /
'     ExpressionCollection.CreateExpression("Number","名=值") / UF EditExp(仅编辑已存在) / CloseAll 两参数
