📚 Description

This pull request adds nuxt-cryptography to the modules listing.

nuxt-cryptography is a lightweight and dependency-free module that provides cryptographic helpers:

• A composable (useCrypto) for encryption, decryption and hashing
• Server-only helpers for sensitive operations
• PBKDF2 key derivation
• Small surface area and predictable API

The module aims to give developers a simple and safe way to perform common cryptographic tasks inside Nuxt projects without pulling in heavy third-party libraries.
