feat(ios): implement Phase 1 permission methods and fix build issues

Implement checkPermissionStatus() and requestNotificationPermissions()
methods for iOS plugin, matching Android functionality. Fix compilation
errors across plugin files and add comprehensive build/test infrastructure.

Key Changes:
- Add checkPermissionStatus() and requestNotificationPermissions() methods
- Fix 13+ categories of Swift compilation errors (type conversions, logger
  API, access control, async/await, etc.)
- Create DailyNotificationScheduler, DailyNotificationStorage,
  DailyNotificationStateActor, and DailyNotificationErrorCodes components
- Fix CoreData initialization to handle missing model gracefully for Phase 1
- Add iOS test app build script with simulator auto-detection
- Update directive with lessons learned from build and permission work

Build Status: ✅ BUILD SUCCEEDED
Test App: ✅ Ready for iOS Simulator testing

Files Modified:
- doc/directives/0003-iOS-Android-Parity-Directive.md (lessons learned)
- ios/Plugin/DailyNotificationPlugin.swift (Phase 1 methods)
- ios/Plugin/DailyNotificationModel.swift (CoreData fix)
- 11+ other plugin files (compilation fixes)

Files Added:
- ios/Plugin/DailyNotificationScheduler.swift
- ios/Plugin/DailyNotificationStorage.swift
- ios/Plugin/DailyNotificationStateActor.swift
- ios/Plugin/DailyNotificationErrorCodes.swift
- scripts/build-ios-test-app.sh
- scripts/setup-ios-test-app.sh
- test-apps/ios-test-app/ (full test app)
- Multiple Phase 1 documentation files
