Update @tuki0918/seeded-shuffle from v0.1.0 to v1.0.0
- Split tsconfig.json into base and specific configurations for core and node packages. - Updated compiler options for build configurations to align with ES2022 standards. - Adjusted module resolution and output settings for better compatibility.
Split tsconfig.json into editor and build configurations for @image-shield/core and @image-shield/node workspaces
- Add CLI commands for encrypting and decrypting images. - Implement command-line options and validation for input and output paths. - Create README.md for CLI usage instructions. - Update package.json and TypeScript configurations for CLI development.
- Moved command registration to separate files for better organization. - Implemented command handling for encrypt and decrypt functionalities. - Added validation functions for input paths and output directories. - Updated type definitions for command options.
- Refactored build and check scripts to use workspace-specific commands for better modularity. - Added separate scripts for building and checking packages.

@copilot ブラウザ向けの実装のため、Buffer の代わりに File | Blob | ArrayBuffer | Uint8Array | Uint8ClampedArray に置き換えて下さい |

完了しました。@image-shield/browserパッケージ内のすべてのBuffer使用を以下のブラウザ互換タイプに置き換えました:
主要な変更点:
すべてのテスト(9/9)と型チェックが正常に通過し、ブラウザネイティブタイプでの完全な動作を確認済みです。 Commit: bd3de13 |

@copilot 1つの画像はシャッフルの復元できますが、複数の画像の場合、正しくシャッフルの復元ができません |
問題を特定し修正しました。複数画像のシャッフル復元が正しく動作しない原因はファイルの順序でした。 ブラウザでファイル選択時に、フラグメントファイルの順序が保証されないため、復元アルゴリズムが期待する順序(fragment_1, fragment_2, etc.)と異なる順序で処理されていました。 修正内容:
これで単体画像と複数画像の両方で正しくシャッフル復元が動作します。 Commit: b31e47f |

暗号化複合の問題を特定し、Node.js版とブラウザ版間の完全な互換性を確保するための包括的なテストスイートを追加しました。 追加されたテスト:
テスト結果: 9つの互換性テストがすべて成功し、文字列・バイナリデータ両方でクロスプラットフォーム暗号化/複合の完全な互換性が検証済みです。 Commit: 249ea20 |

Implementation Details
The browser package follows the same architecture as
@image-shield/nodebut replaces Node.js-specific APIs with browser-native alternatives:cryptomoduleBrowser-Native Type Usage
All Buffer usage has been replaced with appropriate browser-compatible types:
Quality Assurance
The implementation maintains full compatibility with the existing
@image-shield/corearchitecture while providing browser-specific optimizations and user experience enhancements using only browser-native types. The file ordering fix ensures that multiple image restoration works correctly regardless of the order users select files in the browser. The crypto compatibility fix ensures that encrypted content created by the Node.js version can be seamlessly decrypted in the browser.Cross-platform compatibility has been comprehensively verified with automated tests demonstrating that Node.js-encrypted content can be successfully decrypted in the browser environment using string and binary data verification.
Fixes #33.
