How to set up and validate locally

Check the update in Rails.

1. Set GITLAB_SIMULATE_SAAS=0 in your GDK/Rails environment variable

2. Update your add-on to only have duo_core

   GITLAB_SIMULATE_SAAS=0 bundle exec 'rake gitlab:duo:setup[duo_core]'

3. Generate a JWT token

   token = Gitlab::AiGateway.cloud_connector_token('generate_embeddings_codebase', User.first)

4. Decode the token

   decoded_hash = JWT.decode(token, nil, false)

5. Verify that the scopes include the generate_embeddings_codebase unit primitive

   decoded_hash.first['scopes'].include?('generate_embeddings_codebase')
   => true

   Additional verification: without the update, this should return false.
