feat(macos): Ulk.app v0.2 — XcodeGen + typed JSON parsing + first functional toggle

[izo]

Summary

Suite logique de PR #143 (v0.1 mergée). Quatre commits atomiques :

1. test(cli) — framework/cli/cmd/json_contract_test.go : 3 tests Go qui verrouillent le shape de ulk status/doctor/check --json
2. feat(macos) — Modèles Swift StatusReport/DoctorReport/CheckReport (Ulk/Models/UlkReports.swift) miroir du contrat Go ; UlkBridge.status()/doctorReport()/check() typés ; SystemSnapshot.statusReport peuplé depuis le vrai state.json
3. build(macos) — XcodeGen remplace le projet Xcode hypothétique : project.yml (~80 lignes YAML, source de vérité) ; .xcodeproj gitignored
4. feat(macos) — 1er toggle fonctionnel end-to-end (suppression skill community/opt-in via FileManager + alert SwiftUI) ; CI macOS-app passée à 2 jobs parallèles (SwiftPM + XcodeGen/xcodebuild) ; spec card v0.2

Contrat JSON Go ↔ Swift

Pierre angulaire de cette PR. Les deux côtés sont liés par un test :

                  ┌──────────────────────────────────────┐
   ulk status     │  framework/cli/cmd/                  │
   ulk doctor ──→ │  json_contract_test.go               │ ──┐
   ulk check      │  asserts JSON shape stable           │   │ break
                  └──────────────────────────────────────┘   │ on
                                                              │ either
                  ┌──────────────────────────────────────┐   │ side
   SwiftUI app ←─ │  apps/macos/Ulk/Ulk/Models/          │ ──┘
                  │  UlkReports.swift                    │
                  │  (StatusReport/DoctorReport/...)     │
                  └──────────────────────────────────────┘

Test plan

• cd framework/cli && go test ./cmd/ -run "TestStatusJSONContract|TestDoctorJSONContract|TestCheckJSONContract" → ok
• cd apps/macos/Ulk && swift test (CI macos-14 — SPM job)
• cd apps/macos/Ulk && xcodegen generate && xcodebuild -project Ulk.xcodeproj -scheme Ulk build (CI macos-14 — xcodegen job)
• Smoke test manuel sur macOS 14+ : ouvrir Ulk.app, vérifier qu'un skill community apparaît avec une corbeille → confirmer suppression → recharge auto

Limites assumées (v0.2.1+)

• Toggles MCPs et CLIs : pas wired (ce PR couvre uniquement Skills comme proof end-to-end)
• Recherche globale highlight : pas implémentée
• Notifications natives macOS : pas implémentées
• Sparkle réel : v0.3 (besoin Apple Developer credentials)

Note sur l'autre check rouge attendu

Le job pré-existant Go CLI > Coverage gate (issue #144) va probablement échouer ici aussi car cette PR touche .github/workflows/**. Ce n'est pas une régression de cette PR — la couverture du package cmd est à 18% sur main. Voir #144 pour le fix.
