Delete Language Model Endpoint

Remove a language model configuration.

Permanently removes the specified language model from the system. This removes both the cached instance and the configuration, so the model cannot be used until it is added again. The change is persisted to the configuration file.

This operation is useful for:

• Removing models that are no longer needed
• Clearing failed models before adding a corrected configuration
• Freeing resources used by unused models

Returns 404 if the language model does not exist.
