README: repoint hero images to the fresh Qwen3.5-4B showcase

The two top images still pointed at the pre-run figures; swap them for the real
mfq2 map/range from this run and drop the orphaned old PNGs.

 runs many questionnaires; the default is the Clifford moral-foundation vignettes (MFV).

 The map places 19 human societies (grey, MFQ-2 means from Atari et al. 2023) and a local model
 (baseline plus steered poles) on the same relative-emphasis axes. The question the repo is built
 around: where does a model land relative to human cultures, and can we steer it across that space.

-The range plot is the second view: each steering vector's c-sweep (blue = negative pole, red =
-positive) over the grey human cross-cultural band, per foundation. It answers "does any steer push
-a foundation outside the human range" at a glance.
