Unrent

Reclaim overpaid rent from Solana token accounts. SIMD-0437 lowers lamports_per_byte from 6,960 to 696 in five steps; existing accounts keep their old, higher deposit until it is withdrawn. UNRENT scans a wallet and returns the excess: WithdrawExcessLamports (accounts stay open) and CloseAccount (empty accounts). Non-custodial and no API key: build_reclaim returns unsigned transactions that your wallet signs; submit_reclaim checks and sends them. Agents without the wallet's key can hand the use
