feat: Docker化部署 - 單容器架構轉換
將 Tool_OCR 從 macOS conda 環境轉換為 Docker 單容器部署方案。 前後端整合於同一容器，通過 Nginx 反向代理，僅對外暴露單一端口。 ## 新增功能 - Docker 單容器架構（Frontend + Backend + Nginx） - 多階段構建優化鏡像大小 - Supervisor 進程管理 - 健康檢查機制 - 完整部署文檔 ## 技術細節 - 對外端口：12015（原 12010 已被佔用） - 內部架構：Nginx(12015) → FastAPI(8000) - 前端靜態文件由 Nginx 直接服務 - API 請求通過 Nginx 反向代理 ## 系統依賴完善 - libmagic1：文件類型檢測 - LibreOffice：Office 文檔轉換 - paddlex[ocr]：PP-StructureV3 版面分析 - 中日韓字體支援 ## 配置調整 - 環境變數路徑：macOS 路徑 → 容器絕對路徑 - 前端 API URL：修正為統一端口 12015 - Pip 安裝：延長超時至 600 秒，重試 5 次 - CRLF 轉換：自動處理 Windows 換行符 ## 清理 - 移除臨時文檔（API_FIX_SUMMARY.md 等 7 個文檔） 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
