// Package empty provides a no-operation token storage implementation.// This package is used when authentication tokens are not required or when// using API key-based authentication instead of OAuth tokens for any provider.package empty // EmptyStorage is a no-operation implementation of the TokenStorage interface.// It provides empty implementations for scenarios where token storage is not needed,// such as when using API keys instead of OAuth tokens for authentication.type EmptyStorage struct {	// Type indicates the authentication provider type, always "empty" for this implementation.
