Adopt the realism pass and refresh screenshots/docs

- add the v2 runtime picks: per-phase skyline panoramas, brick, sidewalk
  pavers, dry/wet asphalt, awning canvas, and their normal maps
- add the realism tooling and evidence: tools/scene_concepts.py, capture_realism.gd,
  concept frames, reports/sheets, and tests
- retune phase lighting/fog/exposure, add sun yaw, brighten the night glow,
  add the flashlight beam mesh, and rebuild the planter/tree assets
- regenerate all eleven staged screenshots from the current build; compare is
  11 good / 0 bad
- finish the visual-alignment closeout in DONE/TODO, update architecture,
  blender-assets, PLAN, and ignore rules (editable Blender sources untracked)
- keep the judge retry and document the verified default judge model

Verification: headless 227/227; Python tooling 86/86; check_screenshots 11/11.
