+/**
+ * useFileEditor — resolves which registered editor can handle a given MIME type.
+ *
+ * Other modules register editors at the `documents_file_editor` integration
+ * point by including an entry in their `integrations.ts`:
+ *
+ * ```ts
+ * documents_file_editor: [{
+ *   id: 'my_editor',
+ *   meta: { mimeTypes: ['text/plain'] },
+ *   component: () => import('./components/MyEditor.vue'),
+ * }]
+ * ```
+ *
+ * Editor components receive the props:
+ *   `entity: EntityObject`, `mime: string`,
+ *   `readFile: (entityId: string) => Promise<string | null>`,
+ *   `writeFile: (entityId: string, content: string) => Promise<number>`
