Turn barrels off

Set output.barrel to false so no root index.ts is written and every plugin without its own output.barrel inherits the false.

kubb.config.ts

import { defineConfig } from 'kubb/config'
import { pluginTs } from '@kubb/plugin-ts'

export default defineConfig({
  input: './petStore.yaml',
  output: { path: './src/gen', clean: true, barrel: false },
  plugins: [pluginTs()],
})
