重构答题系统：组件拆分、进度跟踪、完成统计

主要改动：
1. 组件拆分：将Question.tsx(605行)拆分为4个子组件(303行)
   - QuestionProgress: 进度条和统计显示
   - QuestionCard: 题目卡片和答题界面
   - AnswerResult: 答案结果展示
   - CompletionSummary: 完成统计摘要

2. 新增功能：
   - 答题进度条：显示当前进度、正确数、错误数
   - 进度保存：使用localStorage持久化答题进度
   - 完成统计：答完所有题目后显示统计摘要和正确率
   - 从第一题开始：改为顺序答题而非随机

3. UI优化：
   - 移除右上角统计按钮
   - 移除底部随机题目、题目列表、筛选按钮
   - 移除"开始xxx答题"提示消息
   - 简化页面布局

4. 代码优化：
   - 提高代码可维护性和可测试性
   - 单一职责原则，每个组件负责一个特定功能

+# 答题组件说明
+
+本目录包含答题功能的子组件，从原来的 `Question.tsx` 大组件拆分而来。
+
+## 组件列表
+
+### 1. QuestionProgress.tsx
+**功能**: 显示答题进度条和统计信息
+
+**Props**:
+- `currentIndex`: number - 当前题目索引
+- `totalQuestions`: number - 总题目数
+- `correctCount`: number - 正确题目数
+- `wrongCount`: number - 错误题目数
+
+**职责**:
+- 显示当前答题进度（百分比和题号）
+- 显示正确和错误的统计数量
+- 使用渐变色进度条增强视觉效果
+
+---
+
+### 2. QuestionCard.tsx
+**功能**: 显示单个题目的卡片，包含题目内容、选项和答案提交
+
+**Props**:
+- `question`: Question - 题目对象
+- `selectedAnswer`: string | string[] - 选中的答案
+- `showResult`: boolean - 是否显示答题结果
+- `answerResult`: AnswerResult | null - 答题结果
+- `loading`: boolean - 提交加载状态
+- `autoNextLoading`: boolean - 自动下一题加载状态
+- `onAnswerChange`: (answer: string | string[]) => void - 答案变更回调
+- `onSubmit`: () => void - 提交答案回调
+- `onNext`: () => void - 下一题回调
+
+**职责**:
+- 根据题目类型渲染不同的答题界面（单选、多选、填空、简答、判断）
+- 处理填空题的特殊渲染逻辑
+- 显示题目编号和分类标签
+- 显示答案结果（使用 AnswerResult 组件）
+- 提供提交和下一题按钮
+
+---
+
+### 3. AnswerResult.tsx
+**功能**: 显示答题结果的Alert组件
+
+**Props**:
+- `answerResult`: AnswerResult - 答题结果对象
+- `selectedAnswer`: string | string[] - 用户选择的答案
+- `questionType`: string - 题目类型
+
+**职责**:
+- 显示正确或错误的提示图标和颜色
+- 显示用户答案和正确答案
+- 显示答案解析（如果有）
+- 特殊处理判断题的答案显示（true/false → 正确/错误）
+
+---
+
+### 4. CompletionSummary.tsx
+**功能**: 完成所有题目后的统计摘要弹窗
+
+**Props**:
+- `visible`: boolean - 弹窗是否可见
+- `totalQuestions`: number - 总题目数
+- `correctCount`: number - 正确数
+- `wrongCount`: number - 错误数
+- `category`: string | undefined - 题目类型分类
+- `onClose`: () => void - 关闭回调（返回首页）
+- `onRetry`: () => void - 重新开始回调
+
+**职责**:
+- 显示完成奖杯图标
+- 展示本次答题的完整统计数据
+- 计算并显示正确率（根据正确率显示不同颜色）
+- 提供返回首页和重新开始两个操作
+
+---
+
+## 组件拆分的优势
+
+1. **单一职责**: 每个组件只负责一个特定的功能
+2. **可维护性**: 更容易定位和修改问题
+3. **可测试性**: 每个组件可以独立测试
+4. **可复用性**: 组件可以在其他页面复用
+5. **代码清晰**: 主组件 Question.tsx 从 600+ 行缩减到 300 行左右
+
+## 主组件 Question.tsx
+
+**保留职责**:
+- 状态管理（题目、答案、进度等）
+- 业务逻辑（加载题目、提交答案、保存进度等）
+- API 调用
+- 组件组合和布局
+
+**文件大小变化**:
+- 重构前: ~605 行
+- 重构后: ~303 行
+- 减少: ~50%
+
+## 使用示例
+
+```tsx
+// 在 Question.tsx 中使用
+<QuestionProgress
+  currentIndex={currentIndex}
+  totalQuestions={allQuestions.length}
+  correctCount={correctCount}
+  wrongCount={wrongCount}
+/>
+
+<QuestionCard
+  question={currentQuestion}
+  selectedAnswer={selectedAnswer}
+  showResult={showResult}
+  answerResult={answerResult}
+  loading={loading}
+  autoNextLoading={autoNextLoading}
+  onAnswerChange={setSelectedAnswer}
+  onSubmit={handleSubmit}
+  onNext={handleNext}
+/>
+
+<CompletionSummary
+  visible={showSummary}
+  totalQuestions={allQuestions.length}
+  correctCount={correctCount}
+  wrongCount={wrongCount}
+  category={currentQuestion?.category}
+  onClose={() => navigate("/")}
+  onRetry={handleRetry}
+/>
