The prompt-enhancer grafts an lm_head onto the shared Qwen3-VL body, so its
forward needs a device guard the stock forward lacks. Applying that patch
globally at load left it active for the whole process, including unrelated
Qwen3-VL users such as the VQA captioner.
Apply the hijack around the enhancer generate call and restore the stock
forward in a finally, so the patch affects only the ideogram enhancer.
