LGTM, same as #1356

test_storage_s3_queue/test_0.py::test_streaming_to_many_views is detected as flaky.

it is likely that it has something to do with the PR that has "S3Queue" in the title 😄

Detailed Failure Analysis

1. uniqTheta aggregate function test

• Reports: x86_64 | aarch64
• Reason: Aggregate function test completely unrelated to StorageDistributed directory parsing changes
• Verdict: Test needs to be updated because of the other changes made in upstream related to aggregate functions.

2. Zero-copy replication tests:

Failed tests across AWS S3, Azure, and MinIO backends:
• zero copy replication/add remove replica parallel
• zero copy replication/add remove one replica
• zero copy replication/bad detached part

The issue: #1338
The fix: ClickHouse#95597

Reports:
• s3_aws_s3_2 x86_64
• s3_minio_2 x86_64
• s3_azure_2 x86_64

3. Job completion error (INFRASTRUCTURE)

• Regression release s3_aws_s3_2 - "Job did not complete"
• Reason: CI infrastructure issue
• Verdict: Infrastructure problem, not caused by PR
