feat: 實現線性雙測驗流程系統

## 主要功能
- 實現線性複習流程：A翻卡 → A選擇 → B翻卡 → B選擇...
- 測驗項目級別的狀態管理和進度追蹤
- 自動測驗類型切換，無需用戶選擇

## 核心改進
- 新增 TestItem 數據結構支援線性流程
- 重構 useReviewSession Hook 管理測驗項目
- 修正延遲計數系統優先級排序邏輯
- 統一兩種測驗的跳過按鈕位置

## 評分標準修正
- 翻卡記憶：一般(1分)以上算答對
- 詞彙選擇：正確選擇算答對
- 答錯的測驗項目不標記完成，會重新出現

## 用戶體驗改善
- 進入頁面自動開始線性測驗
- 清楚的測驗類型和進度指示
- 測驗項目序列可視化
- 延遲計數系統視覺反饋

+### **US-002: 線性複習流程**
+**作為** 想要高效複習的學習者
+**我希望** 系統自動安排複習順序和測驗類型
+**以便** 無需思考如何複習，專注於學習本身
 
-**觸發條件**:
-- ✅ 階段1穩定運行 > 1週
-- ✅ 收到用戶明確反饋需要更多測驗方式
+**核心設計原則**:
+- 🔄 **線性流程** - 用戶不需要選擇，系統決定下一步
+- 📚 **固定模式** - 每張詞卡必須完成兩種測驗
+- ⚡ **自動進行** - 完成一個測驗自動進入下一個
 
-### **功能範圍**
-- 4選1選擇題測驗
-- 模式切換介面
-- localStorage進度保存
+### **詳細流程規格**
+
+#### **2.1 測驗項目生成**
+```
+詞卡A → [翻卡記憶, 詞彙選擇]
+詞卡B → [翻卡記憶, 詞彙選擇]
+詞卡C → [翻卡記憶, 詞彙選擇]
+...
+
+線性序列: A翻卡 → A選擇 → B翻卡 → B選擇 → C翻卡 → C選擇 → ...
+```
+
+#### **2.2 狀態追蹤架構**
+```typescript
+interface TestItem {
+  id: string              // 測驗項目ID
+  cardId: string          // 所屬詞卡ID
+  testType: 'flip-card' | 'vocab-choice'
+  isCompleted: boolean    // 個別測驗完成狀態
+  skipCount: number       // 跳過次數
+  wrongCount: number      // 答錯次數
+  order: number          // 序列順序
+}
+```
+
+#### **2.3 進度計算邏輯**
+- **測驗項目總數**: `詞卡數量 × 2`
+- **當前進度**: `已完成測驗項目數 / 總測驗項目數`
+- **詞卡完成條件**: 兩個測驗項目都標記為已完成
+
+#### **2.4 用戶介面流程**
+1. **進入複習** → 自動開始第一個測驗項目
+2. **完成測驗** → 自動進入下一個測驗項目
+3. **全部完成** → 顯示整體結果統計
+
+#### **2.5 測驗項目詳細設計**
+
+##### **翻卡記憶測驗**
+- **目的**: 自我評估對詞彙的熟悉程度
+- **互動方式**: 點擊翻卡查看定義、例句、同義詞
+- **評分機制**: 3級信心度 (模糊0分、一般1分、熟悉2分)
+- **完成條件**: 用戶選擇任意信心度
+
+##### **詞彙選擇測驗**
+- **目的**: 客觀測試詞彙記憶準確性
+- **互動方式**: 4選1選擇題，根據定義選擇正確詞彙
+- **評分機制**: 正確2分、錯誤0分
+- **選項生成**: 1個正確答案 + 3個隨機干擾項
+- **完成條件**: 用戶點擊任意選項
+
+#### **2.6 延遲計數系統整合**
+- **跳過行為**: 兩種測驗都支援跳過功能
+- **錯誤處理**: 翻卡測驗選擇"模糊"、選擇題答錯都計入錯誤
+- **優先級算法**: 跳過次數 + 錯誤次數 = 延遲分數，越高越優先
+
+#### **2.7 進度保存機制**
+- **範圍**: 個別測驗項目的完成狀態
+- **存儲**: localStorage，包含測驗項目陣列
+- **恢復**: 頁面重新載入時恢復到正確的測驗項目
+- **重置**: 跨日期自動重置進度
