format: email / uri (url) / uuid / date / date-time / time / ipv4 / ipv6 / hostname / phone

制約: minimum / maximum / minLength / maxLength / minItems / maxItems / enum / const / pattern

required: 必須項目は必ず含まれ、その他は 80% の確率で含まれます。

キー名推測: name → 氏名、email → メール、address → 住所、phone → 電話番号など、フィールド名からそれっぽい値を生成します。

未対応: $ref, oneOf/anyOf/allOf, patternProperties, additionalProperties, if/then/else
