Pull request overview

Adds/updates integration tests around versioned-object “delete marker” (S3) / “hide marker” (Backblaze B2) behavior, and adjusts B2 attribute mapping to better represent marker states.

Changes:

• Added new S3 and B2 integration tests validating read/find behavior with delete/hide markers and explicit version IDs.
• Enabled S3 versioning listing in the shared S3 test session setup to exercise version-aware listing paths.
• Updated B2AttributesFinderFeature mapping for hide markers (trashed) and size handling.

File	Description
s3/src/test/java/ch/cyberduck/core/s3/S3ReadFeatureTest.java	Adds a test that reads an explicit version after a delete marker is created and verifies “latest” read fails.
s3/src/test/java/ch/cyberduck/core/s3/S3FindFeatureTest.java	Adds a find test covering behavior differences between versioned and non-versioned paths after a delete marker.
s3/src/test/java/ch/cyberduck/core/s3/S3AttributesFinderFeatureTest.java	Refactors delete-marker assertions and extends coverage to DefaultAttributesFinderFeature.
s3/src/test/java/ch/cyberduck/core/s3/AbstractS3Test.java	Forces s3.listing.versioning.enable=true for the default S3 test session.
dracoon/src/test/java/ch/cyberduck/core/sds/SDSFindFeatureTest.java	Ensures the touched file path is reused and asserts find is false after deleting the room.
