ui(android): a `perry/ui`-only app fails to load because perry-stdlib is not linked

[keufcp]

What happened

An app that imports only perry/ui is linked without perry-stdlib (Linking (runtime-only)...) and fails to load with UnsatisfiedLinkError.

What you expected

The app starts.

Minimal reproduction

import { App, Text } from 'perry/ui';

App({ title: 'ui-only', width: 320, height: 640, body: Text('hello') });

Command you ran:

perry main.ts -o libperry_app.so --target android
# packaged with crates/perry-ui-android/template, installed and launched on the emulator

Environment

• Perry version: 0.5.1591 (193889d)
• Host OS: Debian bookworm x86_64
• Target: android (API 34 emulator)
• Rust toolchain (if building from source): nightly-2026-08-20
• Installed via: from source

Diagnostic output

java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol "perry_ffi_native_async_new" referenced by ".../lib/arm64-v8a/libperry_app.so"

Anything else

libperry_ui_android.a references the perry_ffi_* shims, which are declared in perry-ffi and defined only in perry-stdlib. Linux UI builds already force-link stdlib (build_and_run.rs#L492-L493), as do nativeLibrary manifests (run_pipeline.rs#L2444-L2460); Android has no equivalent. Workaround: void new Headers();.
