Registries

The engine registry maps field/report kind values to definitions.

import { createMlRegistryPack } from "mlform/builtins-ml";
import { createRegistry } from "mlform/schema";

const empty = createRegistry();
const builtins = createMlRegistryPack().registry;

Method	Purpose
registerField(definition)	Add a field kind.
registerReport(definition)	Add a report kind.
getField(kind)	Resolve a field definition.
getReport(kind)	Resolve a report definition.
listFields()	List registered fields.
listReports()	List registered reports.

Duplicate registrations throw RegistryError. Register custom definitions once when the app starts, then reuse the registry.
