// mob_background plugin — Android bridge (foreground-service keep-alive).
//
// Starts / stops the host's BeamForegroundService so the BEAM node keeps
// running when the screen locks or the app is backgrounded. The native thunk
// (nativeRegister) is exported from the sibling zig NIF mob_background_nif.zig.
//
// MobPluginBootstrap.registerAll() calls register() at startup and hands off
// the Activity (MobActivityAware) — the bridge needs an Activity Context to
// start the service.
//
// NOTE: BeamForegroundService is NOT shipped as the bridge class; a foreground
// <service> must be a host-package class declared in the host's
// AndroidManifest.xml. Its source ships alongside this file under
// priv/native/android/BeamForegroundService.kt; copy it into your host package.
