DNF90 服务端与启动器完整源码（含 GM 工具功能增强）

服务端（Go）：
- GM 塞背包/带属性装备发放：在线角色推送 op14 增量物品行，背包实时刷新，无需回角色选择界面
- GM 改金币/改等级：去掉在线拒绝，落库后推送 op14 钱包/op37 等级状态，在线实时刷新
- 等级端点统一切换到新版 GMSetCharacterLevel（自带在线刷新）
- 无限/锁死疲劳模式 + 燃烧疲劳：每房间消耗 2 点、打怪与通关经验双倍
- 燃烧疲劳开关时给所有在线角色推送系统提示（op12 mode 0）
- 深渊史诗掉率：GM 全局倍率 + 城镇增益药剂窗口倍率，真实接入掉落结算

启动器（Python/JS）：
- 标题栏自绘、窗口 1204x717、禁止拖拽改大小、仅最小化/关闭
- GM 工具：疲劳与燃烧、深渊史诗掉率、拍卖行上架（单一定价对齐）
- 拍卖行上架前端对齐服务端单一价格语义，修复 400 报错

+// A Fiend War squad walked into operation area 9 and every encounter attempt was
+// silently refused -- 160 consecutive tries, one per second, all
+// entered=false:
+//
+//	game-dungeon-select-blocked dungeon_id=4957 maze_index=4
+//	  reason=ordinary_dungeon_town_return_origin_unavailable
+//	  error=... origin 1/98/9 does not match runtime 1/98/2
+//
+// The client only saw "the party was disbanded" repeated, because the rejected
+// encounter immediately tore the managed party down again.
+//
+// Root cause: currentDungeonTownReturnOriginOwner returned the fixed waiting
+// area 98/2 for Fiend War, while freeze/commit validate that answer against the
+// session's bound selector origin -- which is the operation area the squad is
+// actually standing in, 98/9. The two must be the same value, so Fiend War has
