android-native: SDL3 APK build for the native client
build-android-native.sh downloads SDL 3.4.16 (sha256-checked), builds libSDL3.so and libmain.so (native_render + port_platform + embedded Python) at API 24, and wraps them in the SDLActivity shell under android-native/ (package org.metin2port.client). push-android-client.sh copies the 40250 Client directory into the app's files/ with run-as (--locale XX selects locale_XX.cfg). port_logic links with --no-dependent-libraries on ELF targets so the verbatim `#pragma comment(lib, ...)` lines do not break lld.
