SpecialX	1f28efbeb6	feat(exams): add section/group structure nodes with auto stats ... Distinguish structural levels from questions: - sectionBlock (new): top-level volume like "第Ⅰ卷 选择题(共24分)" - groupBlock (enhanced): section like "一、选择题" with instruction field - questionBlock (composite): reserved for reading comprehension Key changes: - New section-block.tsx extension with level attr (1=卷, 2=部分) and auto-computed question count + total score in NodeView - group-block.tsx: add instruction field ("每小题3分"), auto stats display - editor-to-structure.ts: recursive buildStructureNode supports arbitrary nesting (section > group > question), computeStats accumulates scores - exam-rich-form.tsx ExamPreview: render section/group/question with distinct styles and stats badges - selection-toolbar.tsx: add "分卷" button (Layers icon) - exam-rich-editor.tsx: register SectionBlock, expose insertSection/ wrapInSection via ref - actions.ts: AI prompt now outputs volumes[] + groups[] structure with instruction; buildTiptapDocFromAiResponse generates nested sectionBlock - i18n: add markSection keys (zh-CN/en) Structural nodes are NOT questions: their question count and total score are automatically computed from child questions, not manually set.	2026-06-24 14:07:29 +08:00
