Module wire 

Wire protocol types for sync stream communication.

This module contains the message types used for all sync protocol communication over network streams:

• StreamMessage: Top-level message wrapper (Init or Message)
• InitPayload: Initial request types (blob share, key share, delta, snapshot, etc.)
• MessagePayload: Response and follow-up message types

Adding New Protocols

To add a new sync protocol’s wire messages:

1. Add request variant to InitPayload
2. Add response variant(s) to MessagePayload
3. Update re-exports in sync.rs

Enums

InitPayload

Initial request payloads for various sync protocols.

MessagePayload

Response and follow-up message payloads.

StreamMessage

Top-level message for sync stream communication.

Constants

MAX_TREE_REQUEST_DEPTH

Maximum depth allowed in TreeNodeRequest.
