> Extract PendingFlush state object from BlockDataStreamOutput

> Key: HDDS-16191
> URL: https://issues.apache.org/jira/browse/HDDS-16191
> Project: Apache Ozone
> Issue Type: Improvement
> Components: Ozone Client
> Reporter: Ren Koike
> Assignee: Ren Koike
> Priority: Major
> Labels: pull-request-available
>
> BlockDataStreamOutput tracks in-flight flush state across several scattered
> fields (putBlockFutures, futures, buffersForPutBlock, totalDataFlushedLength,
> writtenDataLength) that are read and written from multiple methods with
> implicit ordering assumptions.
> Extract these into a PendingFlush object that encapsulates the lifecycle of a
> flush operation. This makes ownership and lifecycle explicit and reduces the
> surface area for ordering bugs.
> The Ratis path has a similar pattern in BlockOutputStream. If this
> abstraction proves effective, it may be applied there in a later phase.
> No behavior change — pure structural refactoring.
