修复Python Killer Wolf文本冒险游戏胜利条件与Inventory重复bug

• 背包重复添加问题修复
  原逻辑判断条件错误，写死检查字符串'item'是否存在于背包中，永远无法命中重复校验，导致可无限重复添加同一物品。修正为：
  1. 单独识别Get开头的物品获取指令，避免和移动指令逻辑混淆
  2. 校验当前输入的物品是否为所在房间的可获取物品
  3. 若物品已存在于背包，直接输出You already have this item，不再重复添加
• 胜利条件逻辑修复
  原逻辑错误，只要背包集齐6个物品就提前弹出恭喜提示，不符合“集齐物品后进入Petting area才触发胜利”的需求。修正为：
  1. 移除原逻辑中无场景判断的集齐物品弹窗
  2. 在进入Petting area的场景判断中新增分支：若背包物品数达到6，输出指定胜利语句You defeated the Killer Wolf so I hope you enjoyed playing.并结束游戏；若不足6则保留原有的被狼击杀的死亡逻辑
  3. 优化物品提示：已获取过的物品不再重复提示“找到新物品”，改为提示已在背包中
