/**
 * Prepares a redeem transaction for a VaultV2 contract.
 *
 * Direct vault call — not routed through the bundler. Redeem has no inflation-attack surface,
 * so skipping the bundler avoids an unnecessary approval and keeps the UX clean.
 *
 * @param params.vault.address - The VaultV2 address.
 * @param params.args.shares - Amount of vault shares to redeem.
 * @param params.args.recipient - Address that receives the redeemed 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<VaultV2RedeemAction>` with `to`, `value`, `data`, and the
 *   typed `action` discriminator the simulation layer consumes.
 * @throws {NonPositiveInputError} when `shares <= 0n`.
 * @example
 * ```ts
 * import { vaultV2Redeem } from "@morpho-org/morpho-sdk";
 *
 * const tx = vaultV2Redeem({
 *   vault: { address: vaultAddress },
 *   args: { shares: 1_000_000n, recipient, onBehalf },
 * });
 * // tx satisfies Readonly<Transaction<VaultV2RedeemAction>>
 * ```
