Code Review

This pull request exposes the WalletConnect relay client ID (wcClientId) in the useAppKitWallets hook by sourcing it from the BlockchainApiController state. The UseAppKitWalletsReturn interface and associated tests have been updated to include this new property. A review comment correctly identifies that adding a new property to the hook's return object constitutes a new feature and suggests updating the changeset versioning from patch to minor to align with semantic versioning standards.

Since this change introduces a new property (wcClientId) to the useAppKitWallets hook return object, it should be classified as a new feature (minor) rather than a patch according to Semantic Versioning (SemVer).
