/**
 * Inject the custom MainActivity.java into the generated Android project.
 *
 * WHY THIS EXISTS
 * ───────────────
 * Capacitor's default MainActivity uses a WebView that silently DROPS
 * `intent:` / `nostrsigner:` URL navigations, so Amber's approval screen never
 * opens and every signing action (delete, accept crew invite, zap, profile
 * edit) hangs forever. Our MainActivity overrides shouldOverrideUrlLoading to
 * launch those intents natively via startActivity() — the real fix that opens
 * Amber, matching how login already works.
 *
 * The android/ folder is generated per-machine (not committed), so we keep the
 * source of truth in android-templates/MainActivity.java and copy it in on
 * every build. Idempotent. Exits quietly if android/ hasn't been generated yet.
