/**
 * Inject the Amber (NIP-55) <queries> block into the Android manifest.
 *
 * WHY THIS EXISTS
 * ───────────────
 * On Android 11+ (and GrapheneOS enforces this strictly), an app can only see
 * or launch another app if it declares a matching <queries> entry. Without it,
 * the nostrsigner intent that opens Amber is SILENTLY blocked by the OS and the
 * native signer call hangs forever — the classic "Waiting for Amber…" bug.
 *
 * Capacitor regenerates android/app/src/main/AndroidManifest.xml on `cap add`
 * and can touch it on sync, so hand-editing is fragile. This script is
 * idempotent and runs automatically as part of the android build, guaranteeing
 * the block is always present in the APK we ship.
 *
 * If android/ hasn't been generated yet (fresh checkout), it exits quietly.
