/**
 * AES-GCM encryption implementation with automatic salt and IV generation.
 *
 * @remarks
 * This class provides secure AES-GCM encryption with the following security features:
 * - Automatic random salt generation (16 bytes) for each encryption
 * - Automatic random IV generation (12 bytes) for each encryption
 * - PBKDF2 key derivation with 100,000 iterations
 * - Authenticated encryption with built-in integrity protection
 * - Secure data format: [salt | iv | ciphertext]
 *
 * @example
 * ```typescript
 * const encryption = new AESGCMEncryption();
 * const config = new AESGCMEncryptionConfig('my-password');
 *
 * const encrypted = await encryption.encryptText('Hello World', config);
 * const decrypted = await encryption.decryptText(encrypted.data, config);
 * ```
