99/99 regression tests pass (+ffi-jni-call-01-parse).
Locks in the same parse-surface contract for the JNI intrinsics
that ffi-objc-call-01-parse pins for the Obj-C side:
#jni_call(*void)(null, null, "getWindow", "()Landroid/view/Window;");
#jni_static_call(s32)(null, null, "max", "(II)I", 3, 7);
#jni_call(bool)(null, null, "isShown", "()Z");
All three lower through the shared `FfiIntrinsicCall` AST node
added in 1.1; only the kind tag distinguishes them. `inline if false`
keeps sema/codegen out of the picture until later phase-1 steps
wire those in.
