feat: A1 短材料复现本单元理解词，并加入黑夜模式
课程内容 - 重写全部 21 个 A1 单元的听读材料，把本单元理解词织进听/读文本， 单元内理解词复现率从约 20% 提升到约 77%（各单元 56–96%）。 - 修正 U01 房间号与机场大巴同为 thirty 的撞车（改为 17/30/40）。 - 校验器容差按级别读取（A1 为 8%），materials 覆盖率、字数、 选项子串等校验全部通过；course_content_test 通过。 黑夜模式 - app_theme 拆分明/暗两套调色板，AppColors 随亮度切换； main 用 theme/darkTheme/themeMode + builder 镜像已解析亮度； 主题偏好持久化到快照；进度页新增“外观主题”切换。 文档 - COURSE-PACK-JSON.md 更新 A1 词池覆盖（840/933）与材料复现约定。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
