THEN Introduce a CustomProvider implementation that assigns a unique provider ID to each instance, includes provider type specification (OpenAI/Anthropic), and allows instance-specific configuration (custom base URLs, API keys). This maintains backward compatibility by using the unique ID as the provider key, thereby breaking the one-to-one constraint while preserving database uniqueness constraints.

// Example conceptual config: custom provider instances with unique IDs
{
  "providers": [
    {
      "id": "custom-openai-1",
      "type": "openai",
      "baseUrl": "https://openrouter.ai/api/v1",
      "apiKey": "env:OPENROUTER_KEY"
    },
    {
      "id": "custom-anthropic-2",
      "type": "anthropic",
      "baseUrl": "https://my-private-proxy.example.com",
      "apiKey": "env:PRIVATE_ANTHROPIC_KEY"
    }
