ccgo 3.4.4

//! Android platform builder
//!
//! Builds native libraries and AAR packages for Android using CMake with NDK.
//! Supports multiple ABIs (arm64-v8a, armeabi-v7a, x86_64, x86).
//!
//! Archive structure matches Python pyccgo output:
//! - lib/{static|shared}/{arch}/ - stripped libraries
//! - symbols/android/obj/{arch}/ - unstripped libraries (in symbols archive)
//! - include/{lib_name}/ - header files
