Get dirname

`dirname` gets the directory portion of a file or path string. It supports static-site-generation helpers that need to locate a file's parent directory before resolving related paths or writing output.

## Signature

```ts
function dirname(path: string): string
```

## Parameters

| Name | Type |
|---|---|
| `path` | `string` |

**Returns:** `string`

## Usage

```ts
import { dirname } from '../src/helper/ssg/utils'

const filePath = 'content/guides/setup.mdx'
const directory = dirname(filePath)

console.log(directory)
```

## AI Coding Instructions

- Pass a path string representing a file or nested resource.
- Use the returned directory path when resolving files relative to the current resource.
- Keep path-format handling consistent with other SSG utilities.
- Check callers that may pass root-level paths or paths without directory segments.
