Subject: [PATCH] [verified] fix: wildcard count correction in CheckWin tile
 count check
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

根因: CheckWin 开头 tiles.Count != 14 检查未计入 wildcardCount,
导致 12 tiles + 2 wildcards = 14 被误判为手牌不足。

修复: tiles.Count + wildcardCount != 14
同步修正鬼牌_1wildcard补刻子测试用13 tiles + 1 wildcard = 14

测试: 33/33 全部通过
