push-notifications

Implement, review, and debug local and remote notifications on iOS/macOS using UserNotifications and APNs. Covers permission flow, token registration, payload structure, foreground handling, notification actions, grouping, and rich notifications. Targets iOS 26+ with Swift 6.2, backward-compatible to iOS 16 unless noted.

Request notification authorization before doing anything else. The system prompt appears only once; subsequent calls return the stored decision.

Always check status before assuming permissions. The user can change settings at any time.
