NFT-DND on OneChain

This workspace contains the first monorepo pass for the NFT-DND concept:

• client uses Next.js 16
• docs uses Nextra
• server uses Express.js
• contracts uses Move for OneChain

Why the blockchain migration changed

The original concept referenced OneChain. This repository is now aligned with the public OneChain developer flow published by OneLabs:

• public RPC endpoints at https://rpc-<network>.onelabs.cc:443
• a Move-based smart contract workflow
• the one CLI for build, environment switching, and publishing
