Phase 6: Push Notifications

[ed-morais]

Goal

Ima comes to the user — not the other way around. Push notifications for morning plans, nudges, and re-engagement.

Checklist

• Functional test: Alex gets nudge at 10:30am, taps it, goes to right screen
• DeviceRegistration model (platform: web/ios/android, push token)
• WebPushProvider (VAPID)
• Notification provider abstraction (base class for FCM/APNs later)
• NudgeEngine service
• Celery beat tasks: morning nudge, mid-day check-in, re-engagement
• DAILY_NUDGE notification content generation
• Frontend: push permission request flow
• Frontend: usePushNotifications hook
• Service worker (sw.js) for web push handling
