transferOwnership

Wrapper function for backward compatibility with legacy code expecting transferOwnership

This function exists to maintain compatibility with contracts that were built against the previous version of Auth where ownership transfer was named transferOwnership The new Auth implementation renamed this to setOwner to better reflect the two-step ownership transfer process. This wrapper ensures existing code like BaseVault continues to work without modification Previous version: https://github.com/transmissions11/solmate/blob/89365b880c4f3c786bdd453d4b8e8fe410344a69/src/auth/Auth.sol New version: https://github.com/transmissions11/solmate/blob/eaa7041378f9a6c12f943de08a6c41b31a9870fc/src/auth/Auth.sol
