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

+// publishRuntimePartyDisbandToSurvivors tells every member a dissolved party
+// left behind that the party is gone.
+//
+// Operator rule (2026-09-22): 「一个人不成队」-- whenever a leave, a kick, a
+// disconnect or a solo dungeon return drops a party to a single member, that
+// member is detached too (RuntimePartyManager.disbandSingleMemberPartyLocked)
+// and this function is what makes the client agree.
+//
+// Two frames, in this order, on purpose:
+//
+//  1. the native kind-2 one-member row. publishRuntimePartyMembershipSnapshot
+//     documents why the aggregate used to be retained: "The native kind-2
+//     transition owns the multiplayer-to-solo confirmation ... silently
+//     clearing the projection here strands the remaining actor on a stale party
+//     model". A disband therefore still hands the client that transition.
+//  2. the party object is cleared - op9 kind-3 record removal with
+//     party_marker=0xffff plus an empty 0x0099 - exactly the projection the
+//     native leave handler publishes for the leaver's own frame
+//     (handleOnlineLeaveParty), and the same "no party" shape the town
+//     peer-selection path proved live on 2026-09-20.
+//
+// The survivor also leaves the attack squad's 编制, mirroring the leaver's
+// unassign in handleOnlineLeaveParty: the squad label is derived from the
+// ordinary party, so a party that no longer exists must not keep claiming one.
+// unassignRuntimeRaidSquadOnPartyLeave skips anyone inside a dungeon run, so a
+// squadmate still fighting a gate is untouched.
