feat: 新增4个番型识别器—三风/双箭刻/一色三同顺/一般高

4个新识别器均基于已有统计逻辑:
- 三风: windKezi==3 (复用大四喜/小四喜的风刻统计)
- 双箭刻: dragonKezi==2 (复用大三元/小三元的箭刻统计)
- 一色三同顺: shunziGroups count>=3 (复用一色四同顺分组)
- 一般高: shunziGroups count>=2

同步更新: enginePatterns + IdentifyFans well-known filter

效果: 国标--check警告 12→6 (消除三风×2/双箭刻×2/三同顺/一般高)
剩余6个: 圈风/门风/单钓将×3/四归一(需新状态跟踪)
