 * 1. Add the provider to LLMProviders enum
 * 2. Create the schema adapter implementing SchemaAdapterInterface
 * 3. Add the adapter to this registry (TypeScript will enforce this)
 * 4. Set to `null` if the provider doesn't support structured output
 *
 * This ensures compile-time safety and forces developers to handle all providers.
