CultMathJson is the JSON twin of CultMathResolver: vectors, quaternion and
Color32 are objects keyed by field name, matrices are arrays of row objects,
rect is {min,max}. Consumers add them with AddCultMathConverters(); CultLib owns
no JSON options. CultCircle and CultSphere serialize and deserialize through
them, with [JsonConstructor] so the struct constructor is used. The Caching
README documents each MessagePack and JSON shape in one table.

GameCult.Geometry no longer carries vector or rectangle values. CultCircle and
CultSphere hold float2/float3, the isosurface and surface-nets extractors take
float3 origin, and the per-call conversion to float3 is gone. Their MessagePack
bytes are unchanged (pinned against the pre-collapse encodings), now produced
by CultMathResolver through the default CultCache options.
This is a breaking change to the GameCult.Geometry public API.
