docs(ios): update roadmap Phase 3 Week 6 with iOS app foundation progress

- Xcode project setup: ✅ (XcodeGen, iOS 17+, zero third-party deps)
- Timer engine Swift port: ✅ (TimerEngine, Cascade, Urgency, Format, TimeBlindness)
- Data models: ✅ partial (CMTimer Codable struct, UserDefaults persistence)
- iOS screens: ✅ (Timeline, CreateTimer, Pomodoro, History, Settings, AlarmOverlay)
- Notification scheduling: ✅ (UNUserNotificationCenter, cascade warnings, actions)
- Haptic engine: ✅ (urgency-mapped feedback patterns)
- XCTest: 58 tests passing (TimerEngine, Cascade, Format)
- Remaining: Recurrence, NLParser, ContextMessages (Phase 2 web deps), SwiftData migration

 ### Week 6: iOS App Foundation
 
-- [ ] **Xcode project setup**
-  - [ ] Multi-target Xcode project: ChronoMind (iOS), ChronoMindWatch (watchOS), ChronoMindMac (macOS)
-  - [ ] Shared Swift package: `Shared/` folder included in all targets
-  - [ ] SwiftData for persistence (or Core Data if SwiftData has issues)
-  - [ ] Dependency: none beyond Apple frameworks (zero third-party for v1)
-  - [ ] Minimum deployment: iOS 17, watchOS 10, macOS 14

-- [ ] **Timer engine Swift port (`Shared/TimerEngine/`)**
-  - [ ] `Cascade.swift` — port from `cascade.ts`

-  - [ ] XCTest unit tests mirroring all Vitest tests from web
-  - [ ] **Estimated effort: 2-3 days** (~500-800 lines, logic is pure computation)
