* Registry for custom test artifact types.
*
* Augment this interface to register custom artifact types that your tests can produce.
*
* Each custom artifact should extend {@linkcode TestArtifactBase} and include a unique `type` discriminator property.
*
* @remarks
* - Use a `Symbol` as the **registry key** to guarantee uniqueness
* - The `type` property should follow the pattern `'package-name:artifact-name'`, `'internal:'` is a reserved prefix
* - Use `attachments` to include files or data; extend {@linkcode TestAttachment} for custom metadata
* - `location` property is automatically injected to indicate where the artifact was created
*
* @example
*  ```ts
* // Define custom attachment type for generated PDF
* interface PDFAttachment extends TestAttachment {
*   contentType: 'application/pdf'
*   body: Uint8Array
*   pageCount: number
*   fileSize: number
* }
*
* interface PDFGenerationArtifact extends TestArtifactBase {
*   type: 'my-plugin:pdf-generation'
*   templateName: string
*   isValid: boolean
*   attachments: [PDFAttachment]
* }
*
* // Use a symbol to guarantee key uniqueness
* const pdfKey = Symbol('pdf-generation')
*
* declare module 'vitest' {
*   interface TestArtifactRegistry {
*     [pdfKey]: PDFGenerationArtifact
*   }
* }
*
* // Custom assertion for PDF generation
* async function toGenerateValidPDF(
*   this: MatcherState,
*   actual: PDFTemplate,
*   data: Record<string, unknown>

*       pageCount: validation.pageCount,
*       fileSize: pdfBuffer.byteLength
*     }]
