feat: 實作全域檔案傳輸機制與 .tar 封裝規範
## 主要變更 ### 新增全域檔案傳輸模組 (src/transfer/) - constants.ts: 定義傳輸常數（10MB 門檻、5MB chunk 大小） - types.ts: 傳輸類型定義 - uploadManager.ts: 後端上傳管理器（支援直傳與 chunk） - downloadManager.ts: 後端下載管理器（支援直傳與 chunk） - archiveManager.ts: 封裝管理器（僅允許 .tar） - index.ts: 統一匯出 ### 新增 API 端點 - uploadChunk.tsx: Chunk 上傳 API - downloadChunk.tsx: Chunk 下載 API ### 前端更新 - public/script.js: 整合智慧傳輸策略（≤10MB 直傳，>10MB chunk） - public/transfer.js: 前端傳輸管理模組 ### 轉換器更新 - mineru.ts: 改用 .tar 格式（不壓縮），禁止 .tar.gz - download.tsx: 使用統一的封裝管理器 ### 測試 - tests/transfer/: 完整傳輸機制測試套件 - tests/converters/mineru.test.ts: 更新以符合 .tar 規範 ### 文件 - README.md: 新增檔案傳輸機制說明 ## 設計原則 - 檔案 ≤10MB：直接傳輸 - 檔案 >10MB：使用 5MB chunks 分段傳輸 - 多檔輸出：僅允許 .tar 封裝（禁止 .tar.gz/.zip） - 引擎層不感知 chunk（僅傳輸層處理）
