refactor: Integrate streamId handling for improved resumable functionality for attachments

- Added streamId parameter to various functions to support resumable mode in tool loading and memory processing.
- Updated related methods to ensure proper handling of attachments and responses based on the presence of streamId, enhancing the overall streaming experience.
- Improved logging and attachment management to accommodate both standard and resumable modes.
