feat(rectification): 少问几道就出卡，交付卡以范围为主（D1–D4）

- D1 引导窗口题每个校正最多 2 道（前端 GUIDED_WINDOW_CASE_LIMIT；引擎
  GUIDED_COLLECT_LIMIT 未动：event_probes.py 属冻结评分身份，改它需重新冻结）
- D2 七条定向线与跳过线重问问完即出卡，没问到的引导窗口不再挡卡，出卡后也不再挂窗口题
- D3 卡头加副标题「最可能 HH:MM」
- D4 前两列相差 ≥5 个百分点才显示相对可能性，否则一句「这几个时刻目前区分不开……」
- 离线回放 scripts/research/fewer_probes_card_replay.py：真值不降、宽度中位 ±1 分钟、提问 11.4→7.8
- Skill 10.0.29 → 10.0.30；DESIGN / VOICE / CHANGELOG / PROGRESS / 真机清单
