Add `aabb: [f32; 4]` field to WireModel (world-space 2-D bounding box). In tessellate_entity() set each wire's AABB from e.as_entity().bounding_box() via new entity_aabb() helper; Insert sub-entities each get their own AABB. Preview/interim wires and any entity returning a zero-extent default box get UNBOUNDED_AABB so they are never pre-rejected. Replace the chord-sphere heuristic in Snapper::wire_in_range() with a proper AABB vs snap-circle overlap test. The new check is four scalar comparisons and correctly handles closed curves (circles, arcs) which the chord-sphere approach had to special-case. Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
