packages/skatespots-background: a local Capacitor Android plugin that polls our
own push-service /pending and raises local notifications. Modes: off / standard
(WorkManager ~15 min) / fast (foreground service ~5 min). Kotlin +
AndroidManifest (POST_NOTIFICATIONS, FOREGROUND_SERVICE_DATA_SYNC, WAKE_LOCK,
battery-exemption) + Gradle module. Client: useBackgroundDelivery (registers a
poll token via NIP-98, seeds the plugin) + a Background delivery (Android)
control in NotificationSettingsCard. The app registers by NAME, not by importing
the package, so the web bundle is unaffected. UNVERIFIED - needs cap sync + a
device.
