SpotAsyncAlternatives

Solana only, present only when non-empty: routes that do NOT settle in the signed transaction (Nest RWA shares: USDC → share mints over CCTP → Plume → LayerZero; share → USDC queues Nest's async redemption). Never part of quotes[] and never ranked against it — a client must show settlement before offering one. See NEST_SOLANA.md.
