/**
 * Type schema info of the Claude.
 *
 * `IClaudeSchema` is a type schema info of the Claude function calling.
 *
 * `IClaudeSchema` seems fully supporting the JSON schema definition of the OpenAPI v3.1
 * specification; {@link OpenApiV3_1.IJsonSchema}. By the way, as the
 * {@link OpenApiV3_1.IJsonSchema} has too much ambiguous and duplicated expressions,
 * `IClaudeSchema` is designed to be clear and simple for the Claude function calling,
 * by utilizng {@link ILlmSchemaV3_1} which has been transformed from the
 * {@link OpenApi.IJsonSchema} for the convenience and clarity.
 *
 * Therefore, `IClaudeSchema` does not follow the entire specification of
 * the OpenAPI v3.1. It has own specific restrictions and definitions. Here is the
 * list of how `ILlmSchemaV3_1` is different with the OpenAPI v3.1 JSON schema.
 *
 * - Decompose mixed type: {@link OpenApiV3_1.IJsonSchema.IMixed}
 * - Resolve nullable property: {@link OpenApiV3_1.IJsonSchema.__ISignificant.nullable}
 * - Tuple type is banned: {@link OpenApiV3_1.IJsonSchema.ITuple.prefixItems}
 * - Constant type is banned: {@link OpenApiV3_1.IJsonSchema.IConstant}
 * - Merge {@link OpenApiV3_1.IJsonSchema.IAnyOf} to {@link IClaudeSchema.IOneOf}
 * - Merge {@link OpenApiV3_1.IJsonSchema.IAllOf} to {@link IClaudeSchema.IObject}
 * - Merge {@link OpenApiV3_1.IJsonSchema.IRecursiveReference} to {@link IClaudeSchema.IReference}
 * - Do not support {@link OpenApiV3_1.IJsonSchema.ITuple} type
 *
 * If compare with the {@link OpenApi.IJsonSchema}, the emended JSON schema specification,
 *
 * - {@link IClaudeSchema.IParameters.$defs} instead of the {@link OpenApi.IJsonSchema.schemas}
 * - Do not support {@link OpenApi.IJsonSchema.ITuple} type
 * - {@link IClaudeSchema.properties} and {@link IClaudeSchema.required} are always defined
 *
 * For reference, if you've composed the `IClaudeSchema` type with the
 * {@link IClaudeSchema.IConfig.reference} `false` option (default is `false`), only the
 * recursive named types would be archived into the {@link IClaudeSchema.IParameters.$defs},
 * and the others would be escaped from the {@link IClaudeSchema.IReference} type.
