rollbackStrategy
Determines the strategy to be used for rolling back the agent's state to a previously saved checkpoint.
This property uses the RollbackStrategy enum to specify the extent of data restoration during a rollback:
RollbackStrategy.Default: Restores the entire state, including message history and other context data.
RollbackStrategy.MessageHistoryOnly: Restores only the message history while retaining other parts of the context.
Defaults to RollbackStrategy.Default, ensuring complete rollback functionality unless explicitly configured otherwise.
