Large binary writes can hang after a background upload failure

### Feature Summary

When the background S3 upload fails while `LargeBinaryOutputStream.write` is filling its bounded queue, the upload worker exits but the producer keeps waiting for queue capacity. The write call can hang forever. Closing the stream can hang for the same reason while enqueueing its EOF marker.

Before: an upload failure with a full queue leaves write and close blocked.

Expected: write and close stop waiting and report the recorded upload failure.
