`scripts/install.mjs` fetches a release from the upstream repository and wires
it into the `lib` module. From the `android.zip` asset it installs the Android
variant (`lib-android`):

## How it works

The `testapp` (`MainActivity`) is a minimal WebView host: it serves the builtin
`testbed` bundle (0.2.0) over `https://testbed.wvb/` and loads it on launch, and
wires its updater to the live playground remote
(`https://playground-remote.wvb.dev`, which hosts 0.3.0). It carries **no** test
logic of its own. The scenarios live in the shared
`@wvb-playground/webview-testbed` package and are expressed against the
platform-agnostic `WebviewDriver` from `@wvb-playground/testdriver`.
`testbed` bundle (0.4.0) over `https://testbed.wvb/` and loads it on launch, and
wires its updater to the playground remote for manual use. E2E supplies a local
remote endpoint through the test app's `wvbRemoteUrl` launch argument. The shared
suite fills the testbed's inputs, clicks its buttons and checks rendered results.
It downloads 0.4.1 and 0.4.2, verifies the page version after each installation,
and checks that rollback loads the previous UI. Downloads use the Android
emulator's `10.0.2.2` host alias.

The Appium session is switched into the testapp's **WEBVIEW** context, then the
suite runs through `createAppiumDriver(driver, { baseURL: "https://testbed.wvb" })`,

## Prerequisites

- The Android SDK, with `platform-tools` (adb) and `emulator` available. Set
`ANDROID_HOME` (or `ANDROID_SDK_ROOT`) if it is not at the platform default.
- At least one AVD. The first one is used unless `ANDROID_AVD` is set; an
already-booted device/emulator is reused.
already-booted emulator is reused. Physical devices are skipped because the
fixture remote uses the emulator's `10.0.2.2` host alias.
- Node + a package manager (the repo pins toolchain via `mise`).

into `~/.appium` on first run.

Clean up the fixture remote when context creation fails.

If remote() rejects or switchToWebview() times out, createTestContext never returns a context. The fixture HTTP server remains open. The Appium server and any emulator started by this call also remain running. Clean up resources acquired during creation before rethrowing the error.

Update createTestContext to clean up all resources acquired during setup,
including the fixture remote, Appium server, and emulator, if remote() rejects
or switchToWebview() times out. Ensure cleanup completes before rethrowing the
original error.
