breaking-changeFixed list_artifacts advertising the unsupported “+versionIndex” sort column (backend returns HTTP 400 — only created_at is orderable). Removed the misleading description input from create_run and update_run — W&B’s upsertBucket accepts description in its input schema, but the server silently normalizes it; reads (via get_run or the UI) always return the composite displayName + '\n' + notes, so any caller-supplied description value is discarded. Callers should now use notes for descriptive text; both action details and the notes input description now spell out the actual W&B semantics.
