ArNS authority key (ARNS_KEY)

Set a base58-encoded Solana secret key as ARNS_KEY, or pass a solana-keygen id.json file via --arns-wallet (or a base58 string via --arns-private-key). This key must control the ArNS name being updated.

⚠️ Important: Use dedicated wallets for deployments to minimize security risks. Ensure your upload wallet has sufficient Turbo Credits for uploads.
