feat: add minimal Capacitor test apps for all platforms

- Add Android test app with exact alarm permission testing
- Add iOS test app with rolling window and BGTaskScheduler testing
- Add Electron test app with mock implementations and IPC
- Include automated setup scripts for each platform
- Provide comprehensive testing checklist and troubleshooting guide
- Follow best practices for Capacitor plugin testing

Test apps include:
- Plugin configuration and scheduling validation
- Platform-specific feature testing (Android exact alarms, iOS rolling window)
- Performance monitoring and debug information
- Error handling and edge case testing
- Cross-platform API consistency validation

Setup: Run ./setup-*.sh scripts for automated platform setup
Testing: Each app provides interactive UI for comprehensive plugin validation

Files: 25+ new files across test-apps/ directory

 # Daily Notification Plugin
 
-A Capacitor plugin for scheduling and managing daily notifications on Android devices.
+A Native-First Capacitor plugin for reliable daily notifications across Android, iOS, and Web platforms.
 
-## Features
+## Key Features
 
-- Schedule daily notifications with precise timing
-- Handle system state changes (battery, power, etc.)
-- Support for adaptive scheduling based on device state
-- Background task management
-- Battery optimization support
-- Rich logging system
-- Comprehensive error handling
+- **Native-First Architecture**: Optimized for mobile platforms with offline-first design
+- **Shared SQLite Storage**: Single database file with WAL mode for concurrent access
+- **TTL-at-Fire Enforcement**: Skip stale notifications before delivery
+- **Rolling Window Safety**: Always keep today's notifications armed
+- **Cross-Platform**: Unified API across Android, iOS, and Web
+- **Production Ready**: Comprehensive error handling, performance optimization, and monitoring
+
+## Quick Start
+
+```typescript
+import { DailyNotification } from '@timesafari/daily-notification-plugin';
+
+// Configure and schedule
+await DailyNotification.configure({
+  storage: 'shared',
+  ttlSeconds: 1800,
+  prefetchLeadMinutes: 15
+});
+
+await DailyNotification.scheduleDailyNotification({
+  url: 'https://api.example.com/daily-content',
+  time: '09:00',
+  title: 'Daily Update',
+  body: 'Your daily notification is ready'
+});
