- Introduced a new `Groups` field in the `Attachment` struct to support categorization of attachments. - Integrated `types.MetaInfo` into `ManagerOption` for improved metadata handling. - Added a local uploader for attachments, enabling file uploads from a specified local path. - Updated asset management functions to reflect changes in file metadata and structure.
