feat(tools): rephrase the concept studies as frontal building views

Owner instruction: show the building, its entrance, the neighbouring buildings,
front-on, and drop the close-up detail framing.

- Studies replaced: door-recess / entrance-wide / column-order /
  entablature-cornice / parapet-motto / window-rhythm / street-wall /
  banner-detail -> building-front, building-entrance, building-with-neighbours,
  building-street-front, building-front-oblique, theatre-front-with-neighbours.
- ANCHOR_SUFFIX now permits REFRAMING (step back, zoom out, widen the view) so the
  whole building can fit, while the architecture stays fixed; previously it pinned
  the camera angle to the reference, which forced cropped results.
- Prompts state 'exterior' explicitly (the entrance study otherwise produced an
  interior) and require sky above the roofline and nothing cut off.

Vision pre-check on the regenerated set: building-entrance and building-street-front
read as full-elevation frontal plates; the studies anchored on the tightly cropped
2009 facade photo stay cropped, because the model will not invent the parapet and
sky the photograph does not contain. That limitation is recorded in the study table
comment - a full 6840 plate needs a full-elevation photograph we do not hold.

Tests: 40 pass (study table assertions unchanged).

-| `facade_detail_concepts.py` | Generates architectural detail plates from a local reference photograph with an image model (OpenRouter). `--list` is free and shows which studies have their reference present; `--all`/`--only <name>` generates. Never overwrites (writes `-v2`, `-v3`), writes a `.refgen.json` sidecar per image (model, prompt, source photo, SHA-256), and puts everything under `Art/reference/facade-details/` — gitignored, local-only, never shipped. Costs money per image, so it is never automatic. |
