Add --obfuscate and --split-debug-info options to the release build
command. These options harden the APK against reverse engineering by
obfuscating class/function names and separating debug symbols from
the APK binary. Also add a plain build option for quick verification.

rootProject.file("app/key.properties") was wrong - rootProject points to
android/ so the actual path would be android/app/key.properties, conflicting
with .gitignore and DISTRIBUTION_API_KEY_SETUP.md which both specify
android/key.properties.
Fix: rootProject.file("key.properties") -> resolves to android/key.properties,
consistent with .gitignore and the setup guide.
