feat: 重做阅读找答案题与 AI 情境对话,并归拢本地识别、查词等既有改动

阅读"在对话里找到答案":
- 16 道题全部重写,干扰项真实出现在对话里,靠说话人归属或否定句才能作答
- 选项按题目内容确定性打乱,答案不再固定排第一;听力环节同样处理
- 去掉超纲干扰项、重复题干,收紧自由作答匹配(过去单个字母也能判对)

AI 情境对话:
- 提示词区分"AI 这一句要做什么"与"学习者随后要完成什么",并下发已教词句清单
- JSON 只强制 reply,translation/feedback 可选;不再索要用不上的 slots/evidence
- AI 不可用时页面明确提示当前回复来自内置示范脚本
- 删掉按 stage 下标猜中文翻译的兜底,避免译文与英文对不上
- 整课对话改用逐轮必需表达校验,替换"关键词沾边就算过";修正自由场景正则误伤
- 总结的"完成任务"按实际通过的轮次生成;模型点评只在结束页呈现一次
- 自由场景支持草稿续练(独立存储槽);修正回答轮数文案与永不解锁的场景标注

同时提交此前工作区中累积的改动:SenseVoice 本地识别、查词/句型解析卡、
复习与测评页调整等,并补充对话校验、选项分布和句子解析的测试。
