* feat: add relation_type to avatar info structure and update related components

- Added `relation_type` to the avatar structured info in `info_presenter.py`.
- Updated `AvatarDetail.vue` to utilize the new `relation_type` for displaying avatar relationships.
- Modified `RelationRow.vue` to accept `type` as a prop for enhanced relationship representation.
- Updated `core.ts` to include `relation_type` in the `RelationInfo` interface.
