 * Type checker for raw OpenAPI v3.1 JSON schemas.
 *
 * `OpenApiV3_1TypeChecker` provides type guard functions for
 * {@link OpenApiV3_1.IJsonSchema} (raw, unemended format). For typia's
 * normalized format, use {@link OpenApiTypeChecker} instead.
 *
 * Key v3.1 features: `const` keyword, `type` arrays (`["string", "null"]`),
 * `prefixItems` for tuples, JSON Schema draft 2020-12 compatibility.
