Protocol for extracting an Ltix.Deployment from a custom struct.

Implement this protocol on your own deployment struct so that Ltix.StorageAdapter callbacks can return your struct directly. The library calls the protocol internally to extract the Ltix.Deployment it needs for launch validation. Your original struct is preserved in the Ltix.LaunchContext returned after a successful launch.

defmodule MyApp.ToolDeployment do
  defstruct [:id, :registration_id, :deployment_id, :label]

  defimpl Ltix.Deployable do
    def to_deployment(dep) do
      Ltix.Deployment.new(dep.deployment_id)
    end
  end
end

Ltix.Deployment itself implements this protocol as an identity transform, so existing code that returns %Deployment{} from storage adapter callbacks continues to work.
