feature: /json-to-jsdoc

# The Big Idea

I'd like to host a standalone online tool like https://transform.tools/json-to-jsdoc, but that will break down intermediary types, and also handle enums.

- [ ] JavaScript conversion function (no frameworks or libraries)
- `JSON.stringify(input, null, 2)` to prettify JSON
- Traverses JSON to produce JSDoc
- Checkbox for "treat arrays as enums"
- Order types alphabetically
- "" is type `String`
- "a|b|c" creates a typedef `MyTypeStatusEnum` ?
- [ ] HTML Textareas
- CSS with variables (see MVP.css)

## Example Output: JSON

```js
/** @typedef {object} json
* @property {object} about
* @property {string} about.legalBusinessName
* @property {string} about.website
* @property {string} about.industry
* @property {string} about.countryOfOperation
* @property {string} about.description
* @property {string} about.operations
*/
```

should instead be

```js
/**
* @typedef MyType
* @prop {MyTypeAbout} about
*/

/**
* @typedef MyTypeAbout
* @prop {String} legalBusinessName
* @prop {String} website
* @prop {String} industry
* @prop {String} countryOfOperation
* @prop {String} description
* @prop {String} operations
*/
```

## Example Output: Enums

Maybe any props that are all caps and assigned an array could be considered enums?

```js
/**
* @typedef {"IsPep"|"IsNotPep"} PepOption
*/
Mercury.POLITICALLY_EXPOSED_OPTIONS = ["IsPep", "IsNotPep"];
```

未指定文件、测试或入口点。首先定位独立工具的 JavaScript 转换代码和 HTML textarea UI，然后将实现与所请求的中间类型、enum 处理、字母顺序以及 CSS 变量进行比较；完成的标准是列出的 JSON 和 enum 示例能够生成预期的 JSDoc 输出。

由索引模型根据 Issue 内容生成。
