    Class AdapterFactory

    Factory for creating and managing model adapters.

    Implements the registry pattern to allow dynamic registration of adapter creators for different model providers. This enables a plugin-style architecture where new providers can be added without modifying core code.

    const factory = new AdapterFactory();

    // Register a provider
    factory.register('anthropic', (config) => new ClaudeAdapter(config));

    // Create an adapter
    const result = factory.create({
      providerId: 'anthropic',
      modelId: 'claude-sonnet-4'
    });

    if (result.ok) {
      const adapter = result.value;
      // Use adapter...
    }
