//! JNI facade for Android callers of EasyTier.
//!
//! This file intentionally lists every Java-visible native method exported by
//! `libeasytier_android_jni.so`. The implementation details live in sibling
//! modules so this facade stays readable as an API map.
//!
//! Network management APIs:
//! - `setTunFd(instanceName, fd)`: attach an Android TUN fd to an instance.
//! - `parseConfig(config)`: validate TOML config text.
//! - `runNetworkInstance(config)`: start a local network instance.
//! - `retainNetworkInstance(instanceNames)`: retain named instances and stop the rest.
//! - `listInstances()`: return running instance names and IDs as JSON.
//! - `collectNetworkInfos()`: return running instance info as a JSON string.
//! - `callJsonRpc(...)`: call an exposed EasyTier RPC service with JSON payload.
//!
//! Config server client APIs:
//! - `startConfigServerClient(url, hostname, machineId, secureMode, callback)`:
//!   start the managed remote config client.
//! - `stopConfigServerClient()`: stop the managed client and release its Java callback.
//! - `isConfigServerClientConnected()`: return whether the managed client is connected.
//!
//! Error API:
//! - `getLastError()`: return the latest FFI/JNI error string for the calling thread.
//!
//! Data-plane APIs:
//! - `EasyTierDataPlaneJNI.*`: low-level async op-handle data-plane JNI.
//! - `EasyTierJNI.dataPlane*`: compatibility exports for older callers.
