第十一阶段 stage 2：场外换币台（暗灯招换币客户）

- 新人脉升级“场外换币台”（OtcUnlockPrice 500），附赠一盏暗灯
- 包装原版暗灯工厂：切换顺序末尾加目标 pd_otc（只接管进出这一步，其余交给原切换函数）；顾客工厂写进公开的 StoreClientListDict.storeClientDict，顾客面板与概率走原版逻辑
- 换色：底图换成原版熄灭的暗灯，叠加层画黄绿色光晕（otc_lamp_on），不进存档
- 换币客户（OtcClient）一半卖币、一半买币：卖币并入原收黑币（Domain/Otc.cs 取代 HotCoins.cs，HotCoinSeller 删除），污点比例随机、越脏越便宜、地址来历写进账本；买币三档报价，PLEDGER 转账确认后现金到账，当晚未付作废
- 只在生成顾客的回调窗口里生成报价、写账本（原版取名字也会调用工厂）
- 存档数据版本 4：旧存档出块奖励、NPC 算力按 MiningScale 放大
- 8 种语言文字、手册“换币客户”一节；单元测试
