* shell: refuse s3.bucket.create on an existing bucket CreateEntry without o_excl replaces the bucket entry, dropping every extended attribute: lifecycle configuration, owner, versioning and the irreversible Object Lock flag. Send o_excl so a re-run fails with 'bucket already exists' instead of silently resetting the bucket. * filer: fail exclusive creates when the lookup itself fails CreateEntry discards FindEntry errors, so an o_excl create hitting a transient store failure would take the insert path and upsert over the entry it was meant to preserve. Propagate the lookup error when o_excl is set; non-exclusive creates keep their existing semantics.

Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * shell: synchronize captured requests and assert the exact bucket error The fake filer records CreateEntry requests on the gRPC server goroutine, so reads need the same mutex; the test also now checks for the exact "bucket my-bucket already exists" message rather than any error that mentions existence.
