/**
 * Prepares a withdraw transaction for a VaultV1 (MetaMorpho) contract.
 *
 * Direct vault call — no bundler needed. Withdraw has no inflation-attack surface.
 *
 * @param params.vault.address - The VaultV1 (MetaMorpho) address.
 * @param params.args.amount - Amount of underlying assets to withdraw.
 * @param params.args.recipient - Address that receives the withdrawn assets.
 * @param params.args.onBehalf - Address whose shares are burned.
 * @param params.metadata - Optional analytics metadata attached to the transaction.
 * @returns A deep-frozen `Transaction<VaultV1WithdrawAction>` with `to`, `value`, `data`, and the
 *   typed `action` discriminator the simulation layer consumes.
 * @throws {NonPositiveInputError} when `amount <= 0n`.
 * @example
 * ```ts
 * import { vaultV1Withdraw } from "@morpho-org/morpho-sdk";
 *
 * const tx = vaultV1Withdraw({
 *   vault: { address: vaultAddress },
 *   args: { amount: 500_000n, recipient, onBehalf },
 * });
 * // tx satisfies Readonly<Transaction<VaultV1WithdrawAction>>
 * ```
