fix(opencode/kilo): add top-level name + models Record to ProvidersAsMap

opencode/kilo require top-level 'name' and a 'models' Record<modelID,Model>
in each provider entry for the harness UI to enumerate and display models.
Without 'name', the gateway appears unlabelled; without 'models', the provider
shows no model list in the selector.
