Move the 30 flat modules under src/scene/ into six folders by role: convert (entity→geometry), text (fonts/shaping), model (render models), pick (hit-test/selection/grips/xclip), view (camera/transform/render), cache (block + property caches). pipeline/ is unchanged. Full path migration — all `scene::X` references become `scene::<group>::X`, no compatibility re-exports. render.rs items that were `pub(super)` (parent was scene) become `pub(in crate::scene)` to keep their original scene-wide visibility. No behavior change; build and tests are green. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
