feat: integrate daily notification plugin for native iOS/Android

Add native notification support via @timesafari/daily-notification-plugin
while maintaining existing Web Push for web/PWA builds. Platform detection
automatically selects the appropriate notification system at runtime.

Key Changes:
- Created NotificationService abstraction layer with unified API
- Implemented NativeNotificationService for iOS/Android
- Stubbed WebPushNotificationService for future web integration
- Registered DailyNotificationPlugin in Capacitor plugin system

Android Configuration:
- Added notification permissions (POST_NOTIFICATIONS, SCHEDULE_EXACT_ALARM, etc.)
- Registered DailyNotificationReceiver for alarm-based notifications
- Registered BootReceiver to restore schedules after device restart
- Added Room, WorkManager, and Coroutines dependencies
- Registered plugin in MainActivity.java

iOS Configuration:
- Added UIBackgroundModes (fetch, processing) to Info.plist
- Configured BGTaskSchedulerPermittedIdentifiers
- Added NSUserNotificationAlertStyle

Documentation:
- Created comprehensive integration guide
- Added architecture overview with diagrams
- Created implementation checklist
- Documented platform-specific behavior

Manual Steps Required:
- iOS: Enable Background Modes capability in Xcode
- iOS: Run `pod install` to install CapacitorDailyNotification pod
- Run `npx cap sync` to sync native projects

Platform Support:
- iOS: Native UNUserNotificationCenter (requires Xcode setup)
- Android: Native NotificationManager with AlarmManager
- Web/PWA: Existing Web Push (coexists, not yet wired to service)
- Electron: Ready (uses native implementation)

Status: Phase 1 complete - infrastructure ready for UI integration
Next: Update PushNotificationPermission.vue to use NotificationService

+
+### Native Platform (iOS/Android)
+```
+1. User clicks "Enable Notifications"
+   │
+2. PushNotificationPermission.vue
+   │
+   └─> NotificationService.getInstance()
+       │
+       └─> Returns NativeNotificationService (detected iOS/Android)
+           │
+           └─> nativeService.requestPermissions()
+               │
+               └─> DailyNotification.requestPermissions() [Capacitor Plugin]
+                   │
+                   └─> Native code requests OS permissions
+                       │
+                       └─> Returns: { granted: true/false }
+
+3. User sets time & message
+   │
+4. nativeService.scheduleDailyNotification({ time: '09:00', ... })
+   │
+   └─> DailyNotification.scheduleDailyReminder({ ... })
+       │
+       └─> Native code:
+           - Stores in SQLite
+           - Schedules AlarmManager (Android) or UNNotificationRequest (iOS)
+           - Returns: success/failure
+
+5. At 9:00 AM:
+   - Android: AlarmManager triggers → DailyNotificationReceiver
+   - iOS: UNUserNotificationCenter triggers notification
+   - Notification appears even if app is closed
+```
+
+### Web Platform
+```
+1. User clicks "Enable Notifications"
+   │
+2. PushNotificationPermission.vue
+   │
+   └─> NotificationService.getInstance()
+       │
+       └─> Returns WebPushNotificationService (detected web)
+           │
+           └─> webService.requestPermissions()
+               │
+               └─> Notification.requestPermission() [Browser API]
+                   │
+                   └─> Returns: 'granted'/'denied'/'default'
+
+3. User sets time & message
+   │
+4. webService.scheduleDailyNotification({ ... })
+   │
+   └─> [TODO] Subscribe to push service with VAPID
+       │
+       └─> Send subscription to server with schedule time
+           │
+           └─> Server sends push at scheduled time
+               │
+               └─> Service worker receives → shows notification

+
+## Key Design Decisions
+
+### 1. **Unified Interface**
+- Single `NotificationServiceInterface` for all platforms
+- Consistent API regardless of underlying implementation
+- Type-safe across TypeScript codebase
+
+### 2. **Runtime Platform Detection**
+- No build-time configuration needed
+- Same code bundle for all platforms
+- Factory pattern selects implementation automatically
+
+### 3. **Coexistence Strategy**
+- Web Push and Native run on different platforms
+- No conflicts - mutually exclusive at runtime
+- Allows gradual migration and testing
+
+### 4. **Singleton Pattern**
+- One service instance per app lifecycle
+- Efficient resource usage
+- Consistent state management
+
+## Permission Flow
+
+### Android
+```
+App Launch
+  ↓
+Check if POST_NOTIFICATIONS granted (API 33+)
+  │
+  ├─> YES: Ready to schedule
+  │
+  └─> NO: Request runtime permission
+          ↓
+      Show system dialog
+          ↓
+      User grants/denies
+          ↓
+      Schedule notifications (if granted)
+```
+
+### iOS
+```
+App Launch
+  ↓
+Check notification authorization status
+  │
+  ├─> authorized: Ready to schedule
+  │
+  ├─> notDetermined: Request permission
+  │       ↓
+  │   Show system dialog
+  │       ↓
+  │   User grants/denies
+  │
+  └─> denied: Guide user to Settings
+```
+
+### Web
+```
+App Load
+  ↓
+Check Notification.permission
+  │
+  ├─> "granted": Ready to subscribe
+  │
+  ├─> "default": Request permission
+  │       ↓
+  │   Show browser prompt
+  │       ↓
+  │   User grants/denies
+  │
+  └─> "denied": Cannot show notifications
+```
+
+## Error Handling Strategy
+
+```typescript
+// All methods return promises with success/failure
+try {
+  const granted = await service.requestPermissions();
+  if (granted) {
+    const success = await service.scheduleDailyNotification({...});
+    if (success) {
+      // Show success message
+    } else {
+      // Show scheduling error
+    }
+  } else {
+    // Show permission denied message
+  }
+} catch (error) {
+  // Log error and show generic error message
+  logger.error('Notification error:', error);
+}
+```
+
+## Background Execution
+
+### Native (iOS/Android)
+- ✅ Full background support
+- ✅ Survives app termination
+- ✅ Survives device reboot (with BootReceiver)
+- ✅ Exact alarm scheduling
+- ✅ Works offline
+
+### Web/PWA
+- ⚠️ Limited background support
+- ⚠️ Requires active service worker
+- ⚠️ Browser/OS dependent
+- ❌ Needs network for delivery
+- ⚠️ iOS: Only on Home Screen PWAs (16.4+)
+
+## Storage
+
+### Native
+```
+DailyNotificationPlugin
+    ↓
+SQLite Database (Room/Core Data)
+    ↓
+Stores:
+- Schedule configurations
+- Content cache
+- Delivery history
+- Callback registrations
+```
+
+### Web
+```
+Web Push
+    ↓
+IndexedDB (via Dexie)
+    ↓
+Stores:
+- Settings (notifyingNewActivityTime, etc.)
+- Push subscription info
+- VAPID keys
+```
+
+## Testing Strategy
+
+### Unit Testing
+- Mock `Capacitor.isNativePlatform()` to test both paths
+- Test factory returns correct implementation
+- Test each service implementation independently
+
+### Integration Testing
+- Test on actual devices (iOS/Android)
+- Test in browsers (Chrome, Safari, Firefox)
+- Verify notification delivery
+- Test permission flows
+
+### E2E Testing
+- Schedule notification → Wait → Verify delivery
+- Test app restart scenarios
+- Test device reboot scenarios
+- Test permission denial recovery
+
+---
+
+**Key Takeaway**: The architecture provides a clean separation between platforms while maintaining a unified API for Vue components. Platform detection happens automatically at runtime, and the appropriate notification system is used transparently.

+# Daily Notification Plugin Integration - Summary
+
+**Date**: 2026-01-21  
+**Status**: ✅ Phase 1 Complete  
+**Next Phase**: UI Integration
+
+---
+
+## What Was Completed
+
+### ✅ Plugin Infrastructure
+1. **Plugin Registration**: `src/plugins/DailyNotificationPlugin.ts`
+   - Capacitor plugin registered with full TypeScript types
+   - Native-only (iOS/Android)
+
+2. **Service Abstraction**: `src/services/notifications/`
+   - `NotificationService.ts` - Platform detection & factory
+   - `NativeNotificationService.ts` - Native implementation
+   - `WebPushNotificationService.ts` - Web stub (for future)
+   - `index.ts` - Barrel export
+
+3. **Android Configuration**:
+   - ✅ Permissions added to `AndroidManifest.xml`
+   - ✅ Receivers registered (DailyNotificationReceiver, BootReceiver)
+   - ✅ Dependencies added to `build.gradle` (Room, WorkManager, Coroutines)
+   - ✅ Plugin registered in `MainActivity.java`
+
+4. **iOS Configuration**:
+   - ✅ Background modes added to `Info.plist`
+   - ✅ BGTaskScheduler identifiers configured
+   - ⚠️ **Requires manual Xcode setup** (capabilities)
+
+5. **Documentation**: `doc/daily-notification-plugin-integration.md`
+
+---
+
+## Platform Support
+
+| Platform | Notification System | Status |
+|----------|---------------------|--------|
+| **iOS** | Native (UNUserNotificationCenter) | ✅ Configured |
+| **Android** | Native (NotificationManager + AlarmManager) | ✅ Configured |
+| **Web/PWA** | Web Push (existing) | 🔄 Coexists, not yet wired |
+| **Electron** | Native (via Capacitor) | ✅ Ready |
+
+**Key Feature**: Both systems coexist using runtime platform detection.
+
+---
+
+## Quick Start Usage
+
+```typescript
+import { NotificationService } from '@/services/notifications';
+
+// Automatically uses native on iOS/Android, web push on web
+const service = NotificationService.getInstance();
+
+// Request permissions
+const granted = await service.requestPermissions();
+
+if (granted) {
+  // Schedule daily notification at 9 AM
+  await service.scheduleDailyNotification({
+    time: '09:00',
+    title: 'Daily Check-In',
+    body: 'Time to check your TimeSafari activity'
+  });
+}
+
+// Check status
+const status = await service.getStatus();
+console.log('Notifications enabled:', status.enabled);
+```
+
+---
+
+## Next Steps
+
+### Immediate (Phase 2)
+1. **Update UI Components**:
+   - Modify `PushNotificationPermission.vue` to use `NotificationService`
+   - Add platform-aware messaging
+   - Test on simulator/emulator
+
+2. **iOS Xcode Setup** (Required):
+   ```bash
+   cd ios
+   open App/App.xcodeproj
+   ```
+   - Enable "Background Modes" capability
+   - Enable "Push Notifications" capability
+   - Run `pod install`
+
+### Short-term (Phase 3)
+3. **Wire Web Push**: Connect `WebPushNotificationService` to existing web push logic
+4. **Test on Devices**: Real iOS and Android devices
+5. **Update Settings**: Ensure notification preferences save correctly
+
+---
+
+## Build & Sync
+
+```bash
+# Sync native projects with web code
+npx cap sync
+
+# Build for Android
+npm run build:android:debug
+
+# Build for iOS (after Xcode setup)
+cd ios && pod install && cd ..
+npm run build:ios:debug
+```
+
+---
+
+## Important Notes
+
+### ⚠️ Critical Requirements
+
+**Android**:
+- `DailyNotificationReceiver` must be in AndroidManifest.xml (✅ done)
+- Runtime permissions needed for Android 13+ (API 33+)
+- Exact alarm permission for Android 12+ (API 31+)
+
+**iOS**:
+- Background Modes capability must be enabled in Xcode (⚠️ manual)
+- BGTaskScheduler identifiers must match Info.plist (✅ done)
+- Test on real device (simulators have limitations)
+
+**Web**:
+- Existing Web Push continues to work unchanged
+- No conflicts - platform detection ensures correct system

+# Daily Notification Plugin Integration
+
+**Date**: 2026-01-21  
+**Status**: ✅ Phase 1 Complete - Native Infrastructure  
+**Integration Type**: Native + Web Coexistence
+
+## Overview
+
+The Daily Notification Plugin has been integrated to provide native notification functionality for iOS and Android while maintaining existing Web Push for web/PWA builds. The integration uses platform detection to automatically select the appropriate notification system at runtime.
+
+## What Was Implemented
+
+### 1. **Plugin Registration** ✅
+- **File**: `src/plugins/DailyNotificationPlugin.ts`
+- Registered Capacitor plugin with proper TypeScript types
+- Native-only (no web implementation)
+
+### 2. **Service Abstraction Layer** ✅
+Created unified notification service with platform-specific implementations:
+
+- **`NotificationService.ts`**: Factory that selects implementation based on platform
+- **`NativeNotificationService.ts`**: Wraps DailyNotificationPlugin for iOS/Android
+- **`WebPushNotificationService.ts`**: Stub for future Web Push integration
+
+**Location**: `src/services/notifications/`
+
+**Key Features**:
+- Unified interface (`NotificationServiceInterface`)
+- Automatic platform detection via `Capacitor.isNativePlatform()`
+- Type-safe implementation
+- Singleton pattern for efficiency
+
+### 3. **Android Configuration** ✅
+
+**Modified Files**:
+- `android/app/src/main/AndroidManifest.xml`
+- `android/app/build.gradle`
+- `android/app/src/main/java/app/timesafari/MainActivity.java`
+
+**Changes**:
+- ✅ Added notification permissions (POST_NOTIFICATIONS, SCHEDULE_EXACT_ALARM, etc.)
+- ✅ Registered `DailyNotificationReceiver` (critical for alarm delivery)
+- ✅ Registered `BootReceiver` (restores schedules after device restart)
+- ✅ Added Room, WorkManager, and Coroutines dependencies
+- ✅ Registered plugin in MainActivity
+
+### 4. **iOS Configuration** ✅
+
+**Modified Files**:
+- `ios/App/App/Info.plist`
+
+**Changes**:
+- ✅ Added `UIBackgroundModes` (fetch, processing)
+- ✅ Added `BGTaskSchedulerPermittedIdentifiers` for background tasks
+- ✅ Added `NSUserNotificationAlertStyle` for alert-style notifications
+
+**Still Required** (Manual in Xcode):
+- ⚠️ Enable "Background Modes" capability in Xcode
+  - Background fetch
+  - Background processing
+- ⚠️ Enable "Push Notifications" capability (if using remote notifications)
+
+## Platform Behavior
+
+| Platform | Implementation | Status |
+|----------|---------------|--------|
+| **iOS** | DailyNotificationPlugin (native) | ✅ Configured |
+| **Android** | DailyNotificationPlugin (native) | ✅ Configured |
+| **Web/PWA** | Web Push (existing) | 🔄 Not yet wired up |
+| **Electron** | Would use native | ✅ Ready |
+
+## Usage Example
+
+```typescript
+import { NotificationService } from '@/services/notifications/NotificationService';
+
+// Get the appropriate service for current platform
+const notificationService = NotificationService.getInstance();
+
+// Check platform
+console.log('Platform:', NotificationService.getPlatform());
+console.log('Is native:', NotificationService.isNative());
+
+// Request permissions
+const granted = await notificationService.requestPermissions();
+
+if (granted) {
+  // Schedule daily notification
+  await notificationService.scheduleDailyNotification({
+    time: '09:00',
+    title: 'Daily Check-In',
+    body: 'Time to check your TimeSafari activity',
+    priority: 'normal'
+  });
+}
+
+// Check status
+const status = await notificationService.getStatus();
+console.log('Enabled:', status.enabled);
+console.log('Time:', status.scheduledTime);
+```
+
+## Next Steps
+
+### Phase 2: UI Integration
+- [ ] Update `PushNotificationPermission.vue` to use `NotificationService`
+- [ ] Add platform-aware UI messaging
+- [ ] Update settings storage to work with both systems
+- [ ] Test notification scheduling UI
+
+### Phase 3: Web Push Integration
+- [ ] Wire `WebPushNotificationService` to existing PushNotificationPermission logic
+- [ ] Extract web push subscription code into service methods
+- [ ] Test web platform notification flow
+
+### Phase 4: Testing & Polish
+- [ ] Test on real iOS device
+- [ ] Test on real Android device (API 23+, API 33+)
+- [ ] Test permission flows
+- [ ] Test notification delivery
+- [ ] Test app restart/reboot scenarios
+- [ ] Verify background notification delivery
+
+### Phase 5: Xcode Configuration (iOS Only)
+- [ ] Open `ios/App/App.xcodeproj` in Xcode
+- [ ] Select App target → Signing & Capabilities
+- [ ] Click "+ Capability" → Add "Background Modes"
+  - Enable "Background fetch"
+  - Enable "Background processing"
+- [ ] Click "+ Capability" → Add "Push Notifications" (if using remote)
+- [ ] Run `pod install` in `ios/` directory
+- [ ] Build and test on device
+
+## Build Commands
+
+### Sync Capacitor
+```bash
+npx cap sync
+# or
+npx cap sync android
+npx cap sync ios
+```
+
+### Build Android
+```bash
+npm run build:android
+# or
+npm run build:android:debug
+```
+
+### Build iOS
+```bash
+npm run build:ios
+# or after Xcode setup:
+cd ios && pod install && cd ..
+npm run build:ios:debug
+```
+
+## Important Notes
+
+### Android
+- **Critical**: `DailyNotificationReceiver` must be in AndroidManifest.xml
+- Android 12+ (API 31+) requires `SCHEDULE_EXACT_ALARM` permission
+- Android 13+ (API 33+) requires runtime `POST_NOTIFICATIONS` permission
+- BootReceiver restores schedules after device restart
+
+### iOS
+- **Critical**: Background modes must be enabled in Xcode capabilities
+- iOS 13.0+ supported (already compatible with your deployment target)
+- Background tasks use `BGTaskScheduler`
+- User must grant notification permissions in Settings
+
+### Web
+- Existing Web Push continues to work
+- No conflicts with native implementation
+- Platform detection ensures correct system is used
+
+## Files Modified
+
+### Created
+- `src/plugins/DailyNotificationPlugin.ts`
+- `src/services/notifications/NotificationService.ts`
+- `src/services/notifications/NativeNotificationService.ts`
+- `src/services/notifications/WebPushNotificationService.ts`
+
+### Modified
+- `android/app/src/main/AndroidManifest.xml`
+- `android/app/build.gradle`
+- `android/app/src/main/java/app/timesafari/MainActivity.java`
+- `ios/App/App/Info.plist`
+
+## Troubleshooting
+
+### Android: Notifications Not Appearing
+1. Check that `DailyNotificationReceiver` is registered in AndroidManifest.xml
+2. Verify permissions are requested at runtime (Android 13+)
+3. Check that notification channel is created
+4. Enable "Exact alarms" in app settings (Android 12+)
+
+### iOS: Background Tasks Not Running
+1. Ensure Background Modes capability is enabled in Xcode
+2. Check that BGTaskScheduler identifiers match Info.plist
+3. Test on real device (simulator has limitations)
+4. Check iOS Settings → Notifications → TimeSafari
+
+### Permission Issues
+1. Request permissions before scheduling: `requestPermissions()`
+2. Check permission status: `checkPermissions()`
+3. Guide users to system settings if denied
+
