[bug]: CLI Registry universal items still removes 'use client' from tsx files

[VeiaG]

Describe the bug

I'm trying to open my registry for some useful files, but without framework detection & components.json
'use client' directive is removed from tsx , assuming rsc is false.

My registry.json

 {
      "name": "color-picker",
      "type": "registry:item",
      "title": "Color Picker",
      "description": "A customizable color picker field for PayloadCMS.",
      "files": [
        {
          "path": "registry/fields/color-picker/field.ts",
          "type": "registry:file",
          "target": "~/src/fields/color-picker/field.ts"
        },
         {
          "path": "registry/fields/color-picker/index.tsx",
          "type": "registry:file",
          "target": "~/src/fields/color-picker/index.tsx"
        },
         {
          "path": "registry/fields/color-picker/style.scss",
          "type": "registry:file",
          "target": "~/src/fields/color-picker/style.scss"
        },
         {
          "path": "registry/fields/color-picker/types.ts",
          "type": "registry:file",
          "target": "~/src/fields/color-picker/types.ts"
        }
      ]
    }

Going into URL manually i can see use client, but adding files from this registry removes it.

Affected component/components

CLI

Maybe add changes to this transformer, to only remove 'use client' if config is avaible?
https://github.com/shadcn-ui/ui/blob/main/packages/shadcn/src/utils/transformers/transform-rsc.ts#L6
Something like this?

import { Transformer } from "@/src/utils/transformers"
import { SyntaxKind } from "ts-morph"

const directiveRegex = /^["']use client["']$/g

export const transformRsc: Transformer = async ({ sourceFile, config }) => {
  if (config.rsc) {
    return sourceFile
  }

  // Remove "use client" from the top of the file.
  // Only remove if rsc is actually set as false in config, not on undefined
 if(config.rsc === false){
   const first = sourceFile.getFirstChildByKind(SyntaxKind.ExpressionStatement)
    if (first && directiveRegex.test(first.getText())) {
      first.remove()
    }
  }

  return sourceFile
}

Or, somehow pass if this is universal item in registry, and then skip this transformer.
