- Replaced raw string parameters with validated wrapper types (BucketName, ObjectName, Region, VersionId, etc.) following the "parse, don't validate" pattern - Bucket and object names are now validated at construction time, ensuring compile-time correctness - Added both relaxed (MinIO-compatible) and strict (AWS S3-compliant) validation modes for bucket names
