<!-- CURSOR_SUMMARY --> #354

Description

@garlobrian52

Note

Medium Risk
Introduces a new SignatureType enum value that may affect downstream logic that assumes only types 0–2, potentially impacting order signing/validation flows for clients upgrading.

Overview
Adds a new signature mode, SignatureType.POLY_DEPOSIT_WALLET = 3, documented as ERC-1271 isValidSignature() validation with ERC-7739 nested domain wrapping.

Updates examples/signatureTypes.ts to show how to initialize a ClobClient for a Polymarket Deposit Wallet using the new signature type and wallet address.
