/**
 * SkateSpots launcher activity.
 *
 * SAFE BY DESIGN: this extends the stock Capacitor BridgeActivity and does NOT
 * override the WebViewClient (an earlier custom version did and caused a
 * black-screen crash). The ONLY thing we add is the registration of the
 * ActivityResultLauncher used by AmberIntentPlugin.
 *
 * WHY THE LAUNCHER LIVES HERE
 * ───────────────────────────
 * AndroidX requires registerForActivityResult(...) to be called BEFORE the
 * Activity is STARTED (i.e. during onCreate). A Capacitor Plugin is instantiated
 * too late to register its own launcher, so we create it here and hand it to the
 * plugin via AmberIntentPlugin.setLauncher(). Results are routed straight into
 * AmberIntentPlugin.handleResult().
 *
 * This is the Amethyst NIP-55 pattern: a foreground-intent signer whose result
 * comes back through a properly-registered ActivityResultLauncher — the reliable
 * path that OPENS Amber's Approve/Reject screen and never hangs, on stock Android
 * and on GrapheneOS alike.
 *
 * Injected into the generated android/ project at build time by
 * scripts/inject-main-activity.mjs.
