Help me configure Claude Desktop for MandAPI using its supported third-party inference mode. Check the installed build and whether organization policy permits local configuration. Do not assume a standard Claude account exposes this panel. If available, use Gateway with base https://api.mandapi.com, Bearer authentication and Static API key. Keep the key private. Use the exact account-visible Claude MODEL_ID with Anthropic Messages support; if model discovery omits it, follow the current official inferenceModels format without inventing aliases or context capabilities. Preserve the previous setup, apply locally, restart fully, and guide one short text check plus the matching MandAPI usage check. Report feature limitations and restoration steps. If the panel is unavailable or managed, explain the specific condition and offer the CLI or MandAPI Connect route.
