Full changelog

New Features:

Client: delete() and async delete() accept delete_linked (default False). When True, deleting a memory also removes the older memories it superseded (the v3 linked_memory_ids chain), transitively — the delete-side counterpart of latest_only, so a superseded memory does not resurface after the current one is deleted (#5270)
