/**
 * Builds the bounded ERC-2612 shares-permit requirement used by an in-kind vault exit.
 *
 * Vault V1 uses the standard token permit domain. Vault V2 uses its protocol-specific domain with
 * only `chainId` and `verifyingContract`.
 *
 * @param params.vault - Vault share token, including V1 permit-domain metadata when available.
 * @param params.version - Vault generation selecting the standard V1 or two-field V2 domain.
 * @param params.spender - Registered VaultExitBundlesV1 spender.
 * @param params.owner - Account that owns and authorizes spending of the vault shares.
 * @param params.chainId - Chain on which the vault and spender are deployed.
 * @param params.nonce - Current vault permit nonce for the owner.
 * @param params.amount - Vault-share allowance to authorize.
 * @param params.deadline - Shared permit and bundle deadline.
 * @returns A requirement whose `sign()` result can be embedded in VaultExitBundlesV1 calldata.
 * @throws {UnsupportedChainIdError} when no address registry exists for `chainId`.
 * @throws {UnsupportedErc20ApprovalSpenderError} when `spender` is not the registered VaultExitBundlesV1.
 * @throws {MissingClientPropertyError} from `sign()` when the wallet has no account.
 * @throws {AddressMismatchError} from `sign()` when the wallet account differs from `owner`.
 * @throws {ChainIdMismatchError} from `sign()` when the wallet targets another chain.
 * @throws {InvalidSignatureError} from `sign()` when signature recovery fails.
 * @throws {InvalidPermitDomainChainIdError} from `sign()` when a Vault V1 permit domain targets another chain or omits `chainId`.
 * @throws {InvalidPermitDomainVerifyingContractError} from `sign()` when a Vault V1 permit domain targets another token or omits `verifyingContract`.
 * @throws {UnsupportedPermitDomainExtensionsError} from `sign()` when a Vault V1 permit domain advertises unsupported extensions.
 * @example
 * ```ts
 * import { encodeVaultSharesPermit } from "@morpho-org/morpho-sdk";
 *
 * const requirement = encodeVaultSharesPermit({
 *   vault: vaultData,
 *   version: "vaultV2",
 *   spender: vaultExitBundlesV1,
 *   owner,
 *   chainId: 1,
 *   nonce: 0n,
 *   amount: 1_000_000n,
 *   deadline,
 * });
 * const signature = await requirement.sign(walletClient, owner);
 * // signature satisfies PermitRequirementSignature
 * ```
