Quote a HyperCore spot swap

GET /hypercore/spot-quote

Quote a swap against Hyperliquid's Core order book and return the order to execute. Core spot is separate from the EVM /quote planner (no addresses or calldata — execution is an order). The response's execution.orderRequest is placed via Photon's /api/hypercore/order.
