package.json: 단일 패키지 통합 (정체성 보존, dual main via extraMetadata)

name=@pieroot/nfd2nfc, appId=com.pieroot.nfd2nfc, productName=NFD2NFC 유지.
package.json main=out/lib/index.js (npm 라이브러리 진입점).
electron-builder extraMetadata.main=out/main/index.js (.app asar만 override).
react/react-dom는 devDependencies로 이동 (Vite renderer 번들에 포함).
files 필드로 npm tarball을 out/cli, out/lib, resources만으로 제한.
