// using API key-based authentication instead of OAuth tokens for any provider.

// It provides empty implementations for scenarios where token storage is not needed,
// such as when using API keys instead of OAuth tokens for authentication.

// SaveTokenToFile is a no-operation implementation that always succeeds.
// This method satisfies the TokenStorage interface but performs no actual file operations
// since empty storage doesn't require persistent token data.
//
// Parameters:
//   - _: The file path parameter is ignored in this implementation
//
// Returns:
//   - error: Always returns nil (no error)
