support x-layer

[koo-virtuals]

Note

High Risk
High risk because it introduces new token-bound account (ERC-6551) + ERC-4337 execution and upgrade authorization logic, which is security-critical and easy to misconfigure. Also adds new network/verification settings for X Layer that could affect deployments and contract verification behavior.

Overview
Adds a new token-bound account stack under contracts/tba, including AccountV3/AccountV3Upgradable, a local ERC6551Registry, and supporting modules for locking, permissioned execution, selector overrides via a sandbox, and batch/nested execution, with signature validation supporting both EOA and contract signatures plus ERC-4337 EntryPoint integration.

Updates Hardhat configuration to support X Layer (chainIds 1952/196) with OKLink verification (@okxweb3/hardhat-explorer-verify/okverify), adds the new networks/RPC defaults and hardfork histories, and expands Solidity compiler config to include multiple versions for verification compatibility.

Updates .openzeppelin manifests (and adds a new one for chain 1952) to record additional proxy/implementation deployments and storage layouts for the new/updated on-chain contracts.
