Watch app MVP: XcodeGen project, gateway client, pair, feed, thread, new thread, notifications

SwiftUI watch-only app in watch/, generated by XcodeGen. Codable models mirror
gateway/src/contract.ts, with lenient string enums so new phases or decisions
still decode. A DemoGateway serves fixtures from the docs/api.md examples for
previews and demo mode. Swift Testing covers decoding the documented JSON,
request encoding, notification action parsing and the small view helpers.
