lottery_特码 + SKILL: 修正 v_xg.json Week/Day 字段语义

**2026-08-04 修正**:
v_xg.json Week/Day 实际是 **Nq 期开彩日**, 不是 Qi 期!

验证:
- Qi=083 + Week=周二 Day=04
- Nq=084 (再下次)
- 推测: 083 期开彩日 = 8/4 周二 - 1 个开彩日 = 8/1 周六
- sol.2344a.cc 083 期挂牌日 = 8/1 (✓ 一致)
- 084 期开彩日 = 8/4 周二 (v_xg.json Week/Day)

修改:
1. lottery_特码.py: format_te_ma_result 加 qi_nq 参数
   - header 显示 Qi + Nq + Qi 期推测开彩日
   - main() 自动取 Qi+Nq+Week+Day
2. SKILL.md: 多处改 Week/Day 描述
   - line 89, 92, 261, 269, description
   - 'Week/Day 是 Nq 期开彩日, 不是 Qi 期!'
3. version 1.2.7 不变 (这次是大修描述)

下次跑 cron 会自动按 Qi=083 显示:
  Qi 期推测开彩日: 周二 Day=04 之前 1 个开彩日 (挂牌日 = 开彩日)
