Adds EVENGINE_ANDROID_TEST_APP build mode: the unit_test sources are compiled into libmain.so (SDL entry) and packaged by the existing Gradle APK along with the test assets, so the full zeroerr suite can run on a device via adb logcat. - test/main.cpp: Android runner with LogcatBuf (cout/cerr -> logcat), chdir to <files>/evengine_test, SDL_Init; keeps SDL_main symbol unmangled. - test/PathBesideSource.h: shared pathBesideThisSource helper that maps __FILE__ to the on-device unpacked tree on Android. - EVTestActivity: unpacks assets/test + assets/examples to internal storage and passes an optional --testcase filter from an intent extra. - test/CMakeLists.txt: builds `main` instead of unit_test on Android, excludes desktop-only devtools tests, links Android system libs. - Makefile: build/android-debug-test, sync/android-test-assets, run/android-test-debug, log/android-test targets. - Gradle wrapper bumped to 8.5 for Java 21 compatibility.
