fix: 多牌先手枚举 — 根除只出单张问题

Browse Source 
根因: GetTipCard 在 GameNum≤0(新轮次)时只返回单张候选，
不包含对子/三张/顺子/炸弹等多牌先手方案。

修复:
- 新增 AddMultiCardLeads(): 新轮次枚举全部多牌先手
  - 对子 (GetMultiGroups:2) 三张 (3) 顺子(PokerLogic.GetShunZi) 炸弹(PokerLogic.GetPlayZhaDans)
- GetMultiGroups(): 统计同面值牌数，生成多牌候选
- 两阶段选择: 多牌候选优先，按牌数多少×胜率排序
- GetOutCard集成: 确保引擎收到正确牌型(DuiZi/ShunZi而非假DanZhang)

10局验证: DanZhang 59 | DuiZi 33 | ShunZi 16 | ZhaDan 1
多牌比例: 46% (之前0%)
