📱 手機版導航系統：
- 添加漢堡選單按鈕（三條線 ↔ X 圖示切換）
- 實作手機版下拉選單，包含所有導航項目
- 手機版用戶資訊區域（頭像 + 登出）
- 點擊導航項目後自動關閉選單

🎯 響應式設計改進：
- 桌面版：水平導航條 + 右側用戶資訊
- 手機版：漢堡選單 + 垂直下拉選單
- 當前頁面在手機版以主色調背景高亮

🔧 技術實作：
- 使用 Tailwind 的 md: 斷點控制顯示/隱藏
- useState 管理手機選單開關狀態
- 動態 SVG 圖示切換（選單/關閉）

✅ 解決問題：
- 手機版現在有完整的導航功能
- 所有頁面在手機上都可以正常使用
- 專業級的響應式用戶體驗

🚀 DramaLing 現在完全支援桌面和手機裝置！
