Canonical discrete-dimension query tolerance, shared by points/lines/gsplats.
0.25 × step (fallback quarter-cell of a unit step when no step metadata).
Exported because the points loader's live query path builds its tolerance in
effective-radius-calculator.ts (calculateSpatialQueryTolerance, which is
EffectiveRadiusConfig-aware) and passes it to SpatialQueryBuilder
explicitly, bypassing computeTolerance. That path MUST apply the same
quarter-cell rule for discrete dims, or points regress to the
neighbour-category over-fetch this module fixes.
