feat(android): make APK installable on BlueStacks and other emulators

- Declare touchscreen/faketouch/screen.portrait/screen.landscape as
  uses-feature required=false so emulators (BlueStacks reports faketouch)
  and Play Store device filters do not exclude the app.
- Drop explicit webContentsDebuggingEnabled override so Capacitor
  auto-enables WebView inspection in debug builds (chrome://inspect over
  ADB) and disables in release.
- Document the install + troubleshoot path in README.

+## Running on BlueStacks / NoxPlayer / Android emulators
+
+The APK has no native libraries (`lib/` is empty), so it's architecture-
+independent — same APK installs on x86_64 emulators and ARM phones.
+
+1. Download the APK from the [Actions artifact](https://github.com/tiennm99/loto-android/actions) (debug)
+   or [Releases](https://github.com/tiennm99/loto-android/releases) (signed).
+2. Drag-drop the APK onto the BlueStacks window, or use **Install APK**
+   from the sidebar.
+3. Launch "Lo To" from the BlueStacks home screen.
+
+If the app shows a blank white screen on first launch, open chrome://inspect
+on the host machine while BlueStacks is running, click **Inspect** on the
+WebView, and check the console — the WebView debugging is enabled in debug
+builds (Capacitor default behavior, no INTERNET permission needed because
+chrome://inspect uses ADB).
+
+Manifest declares `touchscreen`, `faketouch`, `screen.portrait`, and
+`screen.landscape` as **optional** so the Play Store and emulators don't
+filter the app out.
