Detailed Description
Runtime cell-type descriptors and the schema-graph mix-ins (IHasFields, ISubTypes).
Descriptors are the runtime, type-erased face of the static cell types. Each cell exposes its descriptor via the CellLike::descriptor() static, and the ParcelRegistry keeps them keyed by kind id so polymorphic dispatch (e.g. MapCell deserialization) can route to the right from_json. See the README "Descriptors and the registry" section.

Coarse runtime classification of a cell type.
Mirrors the eight wire categories: Primitive, the typed and heterogeneous list/map variants, structs, unions, and a Custom escape hatch for user-supplied descriptors.
