NFT upgrade pipeline that mints evolved artwork on demand

Overview
Holders select any NFT from the collection and upgrade its artwork. The service mints the upgraded token and delivers it straight to the holder’s wallet, keeping the mint, the artwork swap, and the delivery in one atomic user-facing action.
What was built
- Wallet-scoped collection scan that surfaces only upgrade-eligible tokens
- Server-side mint and transfer so the upgraded NFT lands directly in the wallet
- Upgrade state tracked per token to keep the operation idempotent
