/**
 * Fetches migratable positions for a user across specified protocols.
 *
 * @param user - The address of the user whose positions need to be fetched.
 * @param client - The client instance to interact with the blockchain.
 * @param options - Additional parameters for the fetch operation.
 * @param options.parameters - Optional parameters for fetching positions.
 * @param options.protocols - List of protocols to fetch positions from.
 *                             Defaults to all supported protocols.
 *
 * @returns A promise resolving to a map of protocols to their respective migratable positions.
 *
 * @example
 * ```typescript
 * import { fetchMigratablePositions, MigratableProtocol } from "@morpho-org/migration-sdk-viem";
 * import { Client } from "viem";
 *
 * const user = "0x123...abc"; // Replace with the user's address
 * const client = new Client({}); // Replace with a properly configured client
 *
 * const positions = await fetchMigratablePositions(user, client, {
 *   protocols: [MigratableProtocol.aaveV2, MigratableProtocol.compoundV3],
 * });
 * console.log(positions);
