feat(tauri): add Tauri v2 Android app wrapper

- Wrap apps/web as Android APK via Tauri v2 WebView (zero web changes)
- Disable default compression feature to avoid brotli/alloc-no-stdlib conflict with Rust 1.96
- Add RGBA icon placeholders
- Add Android keystore to gitignore

APK output: apps/tauri/gen/android/app/build/outputs/apk/
