Full project scaffold: XcodeGen project.yml, Core models/protocols/errors, SMBService (kishikawakatsumi/SMBClient), SFTPService (Citadel 0.9.2), PhotoLibraryService, LANMonitor, BackupEngine, BackgroundTaskManager, all feature UIs (Login, Connect, Browse, Backup, History, Settings), Shared components and theme. Builds clean with zero errors. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
