docs(governance): address PR #169 review — reconcile sprite-era decisions + doc fixes

Tyre: D-244 now references its precedent (D-148 3D camera / D-149 live 3D characters
— D-244 completes that pivot for objects + assets) and reconciles the 5 sprite-era
decisions it touched, all amended 2026-06-17:
- D-043: 'not 3D' / Light2D scoped to overlay layers; in-world is 3D.
- D-044: sprite footprint retired (sim occupancy + visual hierarchy survive).
- D-049: z-stack logical model survives; sprite/CanvasLayer implementation language retired.
- D-066: dual-scale coordinate model + 2x2 geometry minimum survive; sprite-footprint language legacy.

Hoshe (doc QA):
- D-244 broken cross-file anchors fixed ([D-159]->scope.md, [D-241]->process.md).
- renderer/README: bare [D-244] linked; D-019->D-148 camera note; legacy banner over the
  object-sprite workflow sections; resolution-chain output path qualified.
- docs/assets/_templates/sprite.md + README: marked the template legacy object-sprite schema
  (model/texture/artwork template TBD).

+Everything from here down describes the **retired** object-sprite pipeline (#541 spike) — entity/object/wall sprites are no longer the in-world format (objects are 3D `.glb`; characters are 3D meshes). It is kept for reference, and because the camera / lighting / resolution mechanics above are reused for **2D-artwork** rendering. When generating flat artwork, promote outputs to `client/assets/textures` or `client/assets/artwork` (**not** `client/assets/sprites/`) and ignore the entity-sprite footprint / material / deployment specifics below.
