Description

When using a scan from FasterLog there is a WaitAsync method that will wait for new records, once you are done iterating with GetNext, however if you do a scan from FasterKV.Log, you don't have this feature. Is this something that could be implemented?

Research direction

Start by comparing the FasterLog scan entry point and its WaitAsync behavior with scans from FasterKV.Log, focusing on how GetNext iteration is completed. Determine where a corresponding wait operation would belong and how callers should use it. Done means FasterKV.Log scans can wait for new records after iteration, with behavior covered by the relevant scan tests.
