fix(showcase): all 76 pieces run the asset-quality floors; lint enforces it

showcase/README.md makes check_asset_quality part of the asset gate, but 37
of 76 pieces never called it, including wheelbarrow and apothecary-shelf
from the pinned asset-quality reference set, and 9 pieces added after the
rule landed.

- Each of the 37 now imports gallery_asset_quality and calls
  check_asset_quality right after its framing gate, with the hero and stage
  copied from that piece's own check_framing call. The helper's 11 is
  remapped to the piece's next free exit (20-26, computed from its README
  table and every int it already returns), and the README exit table gains
  that row.
- tests/check_render_gates.py also fails any showcase/*/*.py that does not
  import gallery_asset_quality and call check_asset_quality. 76/76 pass;
  removing the call from sundial reports it.
- examples/gallery_asset_quality.py: the report printed "aq_materials ...
  FAIL" when only the dominant-material share exceeded 0.75, while the gate
  (correctly) passed and printed aq_ok. Dominant share is a dropped floor
  (docs/VISUAL-STYLE.md § Asset quality, printed as information), so the
  line now marks the material count and labels the share
  informational-only. Gate behavior unchanged.
- showcase/README.md names the lint; gallery pages regenerated for the
  inlined source.

Proof (local, .scratch/blender-5.2.1-windows-x64, 5.2.1 LTS, EEVEE): each of
the 37 rendered via its README --output command: 37/37 exit 0 with aq_ok
(fence-kit's FenceWood@1.00 dominant share is the informational line above).
No floor bound, so no model needed fixing and no exemption was recorded;
the committed heroes are unchanged because the gates only run before the
render.

Closes #341
