* Subscribe to context updates for a specific spot asset.
*
* @param config - General configuration for Subscription API subscriptions.
* @param params - Parameters specific to the API subscription.
* @param listener - A callback function to be called when the event is received.
* @returns A request-promise that resolves with a {@link WebSocketSubscription} object to manage the subscription lifecycle.
*
* @throws {ValiError} When the request parameters fail validation (before sending).
* @throws {TransportError} When the transport layer throws an error.
*
* @example
* ```ts
* import { WebSocketTransport } from "@nktkas/hyperliquid";
* import { activeSpotAssetCtx } from "@nktkas/hyperliquid/api/subscription";
*
* const transport = new WebSocketTransport(); // only `WebSocketTransport`
*
* const sub = await activeSpotAssetCtx(
* { transport },
* { coin: "@1" },
* (data) => console.log(data),
* );
