Test-add for the jboolean return. JNI `jboolean` is a single byte (0 or 1); sx's `bool` lowers to LLVM `i1` with byte-coercion at the ABI boundary. CallBooleanMethod is at vtable slot 37. IR snapshot captures today's `ret i1 undef`. Next commit adds the `.bool => Jni.CallBooleanMethod` arm.

// Phase 1 step 1.21 (PLAN-FFI.md): `#jni_call(bool)` (jboolean
|
|
// return). JNI's `jboolean` is a single-byte unsigned integer (0 or
|
|
// 1) on every supported ABI; sx's `bool` lowers to LLVM `i1` but the
|
|
// arg/return coercion path widens it to the byte slot the JNI
|
|
// runtime expects. CallBooleanMethod lives at vtable slot 37.
