装备校验链/快捷栏/公会/好友情侣/交易仓库五项差距修复（增量 129）

- 装备校验：can_equip 按 CanEquipNow→FindEquipCell→EquipItem 精确重排，
  新增 find_equip_cell() 1:1 复刻（RING/UNIQUE 占用翻转、COSTUME/BELT/DS），
  帝国 antiflag 降级为 tooltip 提示，LIMIT_PCBANG/REAL_TIME* 语义与倒计时文案
- 快捷栏：死亡全槽禁用+激活守卫、变身（affect 220）技能置灰、
  物品槽失配置灰（服务器回收/换武器后刷新）
- 公会：GUILD_AUTH_* 权限位门控踢人/公告/技能升级，/gskillup、
  被宣战应答弹窗（/war·/nowar）、资金存取行（40250 服务端已禁用仍保留 1:1）
- 好友/情侣：messenger 三固定组（好友/公会/情侣），lover_login/logout/
  near/far/divorce 命令事件→在线/在身边状态与离婚隐藏
- 交易/仓库：ExchangeState.last_notice（ALREADY/LESS_GOLD）结束浮层提示；
  仓库改密 /safebox_change_password 三段输入；关窗补 /safebox_close·/mall_close；
  仓库金钱经核实 40250 无 wire 协议，UI 定界只读
- app_flow：重连时 guild_marks_ready 重复连接加 is_connected 守卫
- 相机 look_at 零向量守卫（首帧/传送落点）
- 测试：equip/love/guild 断言更新，79 项中 78 绿（game_camera_test 为
  HEAD 既有失败）；真服冒烟 LIVE_SMOKE PASS（192.168.21.203 全链路）
- docs/CLIENT-GAP.md 同步增量 129
