Greptile Summary

Adds the missing deviceFamily optional field to the DevicePairRequestedEvent Swift struct in both the macOS app and shared OpenClawKit protocol models, bringing them in sync with the existing TypeScript protocol schema (DevicePairRequestedEventSchema). This is a mechanical protocol sync — the field was already defined server-side and sent by clients, but the Swift decoder was missing it.

• Added devicefamily: String? property, init parameter, assignment, and CodingKeys mapping ("deviceFamily") to DevicePairRequestedEvent in both apps/macos/ and apps/shared/ GatewayModels.swift
• Both files remain identical after the change, as expected

Confidence Score: 5/5

• This PR is safe to merge — it's a mechanical protocol sync adding a missing optional field to Swift models.
• The change adds a single optional String? field to a Codable struct in two identical Swift files. The field already exists in the TypeScript protocol schema, is already sent by clients, and is already handled server-side. The CodingKeys mapping is correct, the placement is consistent with the schema field order, and both files remain in sync. No logic changes, no risk of runtime breakage.
• No files require special attention.
