Pull Request Overview

This PR implements ZkSync-specific support for native order functionality by adapting the contract system to work with ZkSync's unique CREATE2 implementation and bytecode handling.

• Adds ZkSync-specific address computation using ZkSync's custom CREATE2 prefix
• Implements ZkSync-compatible minimal proxy contract for deterministic deployments
• Creates ZkSync variants of native order contracts that use the custom address computation

The pragma version ^0.8.20 is inconsistent with other contracts in this PR that use 0.8.30. Consider using a consistent Solidity version across all contracts for better maintainability.

Suggested change

	pragma solidity ^0.8.20;
	pragma solidity ^0.8.30;

Creating a temporary proxy contract just to get its bytecode hash is inefficient. Consider computing the bytecode hash directly from the proxy's creation code to avoid unnecessary contract deployment in the constructor.

Suggested change

	MinimalProxyZkSync proxySrc = new MinimalProxyZkSync(IMPLEMENTATION);
	bytes32 bytecodeHashSrc;
	assembly ("memory-safe") { // solhint-disable-line no-inline-assembly
	bytecodeHashSrc := extcodehash(proxySrc)
	}
	_PROXY_BYTECODE_HASH = bytecodeHashSrc;
	_PROXY_BYTECODE_HASH = keccak256(MinimalProxyZkSync.creationCode(IMPLEMENTATION));
