refactor: remove copy-object and type definitions; migrate to new S3 structure

- Deleted copy-object.ts and type.ts files as part of the refactor.
- Updated index.ts to export from new S3 core and type files.
- Refactored OssBase class in core.ts to handle file uploads and object management.
- Enhanced error handling for object retrieval and metadata management.
- Introduced new methods for handling object streams and metadata filtering.
- Updated download utility functions to align with new structure.
