Local Android engine artifacts

This directory is intentionally ignored by git. Put reviewed, pinned native artifacts here before making a release APK:

• freeturn.aar — built from the FreeTurn commit recorded in THIRD_PARTY_NOTICES.md.
• libbox.aar — fetched from Leadaxe/sing-box-lx at the version pinned in native/android/libbox.version and verified against release SHA256SUMS.

scripts/build-android.sh extracts classes.jar and jni/* from each AAR into the Flet Android extension because Gradle does not allow a direct local AAR dependency while building the extension AAR. The current APK packages libbox only: FreeTurn and libbox contain incompatible global gomobile runtime classes. Use REQUIRE_NATIVE_ARTIFACTS=1 for a release build.
