The previous run got all the way through compile + link + zipalign and
then died inside apksigner with `IOException: No space left on device`.
Cross-compiling all three Android ABIs (arm64-v8a, armeabi-v7a, x86_64)
in debug mode blows target/ past 25 GB, and by the time apksigner is
streaming the signed APK to disk the runner has nothing left.
Two changes:
1. build_android_apk.sh now reads `ABIS` from the environment (defaults
to all three for backwards compat) and uses it to assemble the
cargo-ndk `-t` flags.
2. android-build.yml passes ABIS=arm64-v8a, since the debug artifact
is consumed by adb-installing to a single arm64 device and the
other two ABIs were dead weight.
Also frees \$STAGING/app-unsigned.apk right after zipalign so it's not
sitting next to the aligned APK and the output APK during signing.
Release workflow is untouched — release APKs still ship all three ABIs.
