feat: 新增 deark 引擎支援解包/解析多種格式

- 新增 deark 轉換器 (src/converters/deark.ts)
- 支援 100+ 種輸入格式（壓縮檔、舊圖片、字型、可執行檔資源等）
- 輸出為 .tar 封裝
- Dockerfile 添加 deark 從源碼編譯安裝
- 更新 main.ts 註冊新引擎
- 添加單元測試 (tests/converters/deark.test.ts)
- 更新文件 (docs/功能說明/轉換器.md)
- CI/CD 添加 deark 版本驗證

+## 檔案解包/解析
+
+### deark
+
+deark 是一個命令列工具，用於解碼和轉換各種二進位格式。它可以解包壓縮檔案、分析舊格式圖片、提取嵌入資源等。
+
+> 📦 **輸出格式**：`.tar` 封裝，包含所有解包出的檔案
+
+**主要功能：**
+- 解包壓縮檔案（ZIP、LHA、ARC 等舊格式）
+- 轉換舊圖片格式（ICO、PCX、BMP 等）
+- 提取可執行檔資源（EXE、DLL 內嵌圖示）
+- 分析字型檔案（FON、FNT、PSF）
+
+<details>
+<summary><strong>輸入格式（100+ 種）</strong></summary>
+
+**壓縮/封存格式：**
+`zip`, `lha`, `lzh`, `arc`, `arj`, `zoo`, `z`, `gz`, `bz2`, `xz`, `cab`, `sit`, `sitx`, `stuffit`, `hqx`, `bin`, `macbin`, `cpio`, `rpm`, `deb`, `ar`, `a`
+
+**圖片格式：**
+`ico`, `cur`, `ani`, `icns`, `bmp`, `dib`, `pcx`, `dcx`, `pict`, `pic`, `pct`, `wmf`, `emf`, `gem`, `img`, `mac`, `msp`, `iff`, `ilbm`, `lbm`, `ham`, `xbm`, `xpm`, `ras`, `sun`, `tga`, `vst`, `icb`, `vda`, `sgi`, `rgb`, `rgba`, `bw`, `int`, `inta`, `psd`, `xcf`, `ora`, `kra`, `psp`, `jbig`, `jbg`, `fpx`
+
+**字型格式：**
+`fon`, `fnt`, `psf`, `bdf`, `pcf`
+
+**可執行檔/資源檔：**
+`exe`, `dll`, `com`, `ne`, `mz`, `res`, `rsrc`, `icl`
+
+**其他格式：**
+`swf`, `fla`, `amiga`, `adf`, `dms`, `d64`, `t64`, `prg`, `crt`, `tap`, `tzx`, `wav`, `riff`, `avi`, `ani`
+
+</details>
+
+| 輸出格式  | 說明                         |
+| --------- | ---------------------------- |
+| `extract` | 解包所有內容（輸出為 .tar）  |
+
+**使用範例：**
+1. 上傳 `.ico` 檔案
+2. 選擇 `deark` 轉換器
+3. 選擇 `extract` 輸出格式
+4. 下載 `.tar` 封裝（包含所有解包的 PNG 圖片）
