Two related Android-only papercuts found while testing build #4 on a Pixel 6:
1. Frontend was crashing in the WebView with:
Tauri/Console: Uncaught (in promise) event.listen not allowed.
Permissions associated with this command: core:event:allow-listen,
core:event:default
The desktop build worked fine because Tauri's default capability set
covers the desktop side. On Android (and iOS) Tauri 2.x is much stricter
about ACL — without an explicit capabilities/default.json that lists
"android" in its platforms, the WebView gets zero permissions. Add a
default capability granting core:default + the event listener perms
across all five platforms (linux/macOS/windows/android/iOS).
2. Every fresh docker run produced a new ~/.android/debug.keystore, so
`adb install -r` of a freshly built APK over an already-installed one
failed with INSTALL_FAILED_UPDATE_INCOMPATIBLE. Mount a persistent host
volume at /home/builder/.android in build-tauri-android.sh so the same
debug keystore is reused across builds and `install -r` keeps working.
