Unstake an LST back to SOL (non-custodial). lst_token is a mint (mSOL/jitoSOL/bSOL); amount in base units. mSOL routes via Marinade, others via the Sanctum router. Returns an UNSIGNED base64 tx. The technology service fee is charged on the unstaked-LST notional past the daily free tier (x402 payment_header). ``idempotency_key`` (optional): a client-generated UUID. Retrying with the same key + same args replays the original result instead of re-unstaking. Reuse the SAME key across the build call and its ``signed_transaction`` completion call -- see liquid_stake; the two legs dedupe independently, so this never raises IDEMPOTENCY_CONFLICT. ``signed_transaction`` / ``verify`` (two-phase execution): see liquid_stake -- re-call with the signed tx and Crank broadcasts it, confirms it on-chain, and re-reads the LST + SOL balances.
