echo 命令:
echo   build         完整建置 (Sidecar + Electron)
echo   sidecar       僅打包 Sidecar
echo   electron      僅打包 Electron (需先打包 Sidecar)
echo   clean         清理建置目錄
echo   help          顯示此幫助訊息
echo.
echo 選項:
echo   --skip-sidecar    跳過 Sidecar 打包
echo   --clean           建置前先清理
echo.
echo 範例:
echo   %~nx0 build               完整建置
echo   %~nx0 sidecar             僅打包 Sidecar
echo   %~nx0 electron --skip-sidecar    僅打包 Electron
echo.
echo 注意:
echo   - 首次打包 Sidecar 需下載 Whisper 模型，可能需要較長時間
echo   - 確保有足夠的磁碟空間 (建議 5GB+)
