//! NDK binder primitives for querying Android system services.
//!
//! Uses `dlopen` on `libbinder_ndk.so` to avoid hard-linking against a library
//! absent from older NDK toolchains or non-Android targets.
//!
//! ## Transaction code resolution
//!
//! Transaction codes are resolved fresh from `framework.jar` DEX on each
//! startup; no persistent cache.
//!
//! ## Observer mode
//!
//! `ActivityManager::open_with_observer` registers this process as an
//! `IProcessObserver` with ActivityManager. Callbacks fire when foreground
//! activities change and signal an `eventfd` that callers can poll via epoll.
//! After the eventfd fires, call `get_focused_package` to read the new value.
