Every pair of bodies sharing the same immediate parent (real siblings —
e.g. two stations orbiting the same planet, or two moons of the same
planet) that are close enough for one to render inside the other's own
sphere. Same "not a data bug, but may render badly" spirit as
findBodiesInsideParent — two real, small bodies can legitimately sit
closer together than their shared generic placeholder radius implies.
Deliberately scoped to bodies sharing a parent, not every pair in the
system (an O(n²) global scan) — a real system can have hundreds of
bodies, but any one parent's own children are typically a handful, so
this stays cheap (bounded by the largest sibling group, not system
size) while still covering the actually-plausible "these two are near
each other" cases: unrelated bodies elsewhere in the system are, by
construction of how real systems are laid out, essentially never close
enough to matter.
