CultMathResolver formats float2/3/4, double2/3, int2/3/4, bool2/3/4,
quaternion, Color32, Random, float2x2, float3x3, rect and CultCellular as
component arrays, and sits in the default CultCache resolver chain so no
consumer registers anything. It lives in GameCult.Caching.MessagePack, which
already owns that chain; CultMath core stays dependency-free.
Vector, rect and Aetheria-formatter byte shapes are pinned by golden tests, a
reflection test fails when a public CultMath value type has no formatter, and
decode skips extra elements and refuses nil.
