- Moves go through `move-multiple` in batches of 150, with an optional
target name per node (`move_nodes_streaming` / `NodeMoveItem`), a single
`InvalidRequirements` retry against the server's current name hash, and
passphrase signing for anonymously created nodes. A batch rejected as a
whole keeps its API error code on every node.
- Share memberships carry invite time and inviter email, and the inviter's
`drive.share-member.inviter` signature is verified as non-fatal metadata
(`verify_detached_with_context`).
- `Node` gains `direct_role` and `share_id`.
- Trashed detection reads `TrashTime` as well as the legacy `Trashed`.
Breaking: new public struct fields on `Node` and `ShareMembership`.
