/**
 * Cross-Chain Vault Registry
 *
 * Address-keyed registry of August's LayerZero OVault deployments plus the
 * resolver helpers that turn a vault address into the
 * {@link ICrossChainVaultConfig} consumed by `buildCrossChainVaultTx`,
 * `crossChainVaultDeposit`, and `quoteCrossChainDeposit`.
 *
 * This is the cross-chain analogue of the SwapRouter registry
 * (`VAULTS_USING_SWAP_ROUTER` / `getSwapRouterAddress`): consumers resolve a
 * full config by vault address instead of hand-assembling the per-chain
 * contract maps and LayerZero EIDs. Without it, every consuming app would
 * re-encode the same address book.
 *
 * Addresses are ported verbatim from upshift-app `src/config/ovault.ts` and
 * cross-checked against the read-side `LAYERZERO_VAULTS` registry in
 * `services/layerzero/deposits.ts`. Verify against the deployed contracts
 * before adding or editing an entry — a wrong address silently routes funds
 * to the wrong chain.
 *
 * Return convention (deliberate, mirrors the SwapRouter helpers): lookups that
 * resolve a single optional value (`getCrossChainVaultConfig`,
 * `getOVaultChains`) return `undefined` for an unregistered vault, while
 * list-returning helpers (`getWithdrawDestinationChains`) return `[]` so
 * callers can iterate without a null-check.
