Help me create a MandAPI custom-model profile for Junie CLI. Inspect the installed version and preserve existing profiles. Use a profile named mandapi with the exact account-visible MODEL_ID, apiType OpenAICompletion, baseUrl https://api.mandapi.com/v1/chat/completions and apiKey ${MANDAPI_API_KEY}. Junie expects the full endpoint URL, not only /v1. Keep the actual key private in the inherited environment. Select custom:mandapi, guide a short read-only README task and check its MandAPI usage. Do not add made-up model limits or Ingrazzio proxy fields. Report the saved profile and how to restore the former model.
