feat(sync): CRDT client protocol for rtmx-sync integration (REQ-GO-042)

Implements the sync protocol layer for rtmx-sync server communication:
- SyncMessage wire format (JSON over WebSocket)
- DatabaseToUpdates: serialize local database for push
- ApplyUpdates: apply server-side merged updates to local database
- RequirementUpdate model with add/update/remove actions
- Encode/Decode round-trip for protocol messages

Design decision: merge logic delegated to rtmx-sync server. The Go CLI
is a thin WebSocket client, not a standalone CRDT engine. This keeps
the open source CLI simple while rtmx-sync handles the complexity.

16 behavioral tests covering serialization, apply semantics, edge
cases (duplicates, nonexistent removes, dependency parsing).

Unblocks REQ-INT-001 (integrity framework) and REQ-INT-002.
