v6.1.12: Chara Dasha KN Rao Benchmark正式通过(95.83%)

PyJHora oracle benchmark 10案例×120字段：
- Sign Sequence: 120/120 = 100.00%
- Duration: 110/120 = 91.67%
- Overall: 230/240 = 95.83% >= 95% ✅ PASS

修复:
- <=0检查顺序对齐PyJHora(先于尊贵调整)
- _PLANET_DIGNITY_KNRAO表(含Rahu/Ketu+set检查+Mercury own sign排除)
- _resolve_chara_dasha_lord()动态宫主判定框架
- bench脚本含Rahu/Ketu行星映射

已知限制: ~4.2%差异来自Aquarius/Scorpio共主动态判定(未来优化)
