swaitsandClaude Opus 4.7 1c2007dcb5 spec(multipart): constrain MULTIPART ACK to direct paths
Add a "Multipart ACK Usage Constraints" subsection making explicit
what upstream enforces in code but the spec previously left implicit:

- MULTIPART-wrapped ACKs MUST only be emitted on direct-routed return
  paths. When no direct path is known, the sender MUST fall back to a
  plain PAYLOAD_TYPE_ACK via flood. Matches sendAckTo() and
  routeDirectRecvAcks() in upstream.
- All MULTIPART and plain copies of the same ACK carry an identical
  4-byte ack_crc; receivers MUST dedup by CRC at the application
  layer (Section 16 packet-hash dedup does not catch them because the
  wrapper byte makes each copy hash-distinct).
- Typical inter-copy delay ~300 ms plus the direct retransmit delay;
  exact count via getExtraAckTransmitCount() (reference default 0).

Validated against upstream meshcore-dev/MeshCore @ 1a7b361
(Mesh::routeDirectRecvAcks, BaseChatMesh::sendAckTo).
