//! JNI emission mode for the Kotlin backend.
//!
//! When `[crates.kotlin] ffi_style = "jni"` (or when forced by the Android
//! backend), this module emits:
//!
//! - `<Module>Bridge.kt` — a Kotlin `object` with `external fun` declarations
//!   and an `init { System.loadLibrary("<crate>_jni") }` block.
//! - `DefaultClient.kt` — a Kotlin class holding a `Long` handle that delegates
//!   every method to the Bridge object via JNI. Streaming methods use the same
//!   `callbackFlow` pattern as the Panama path but reference `handle: Long`
//!   instead of `inner: <JavaFacadeType>`.
//!
//! No `java.lang.foreign.*` imports are emitted anywhere in this module.
