"""
qwen_test_runner.vision — image→JSON benchmark harness.

Extends the text testbed to vision: a per-category task registry (mirroring the
caption SLOT_REGISTRY), coordinate normalization, ground-truth metrics that
replace substring grounding, a multi-model VLM runner over the Qwen3.5 / Qwen3-VL
ladder, and an orchestrator that ranks models for the no-finetune labeler verdict.

The data-driven modules (coords, model_registry, tasks_vision, metrics) are
torch-free and import eagerly. The VLM runner and orchestrator are imported lazily
so `import qwen_test_runner.vision` stays cheap on a CPU box.
