    Manual test instructions for Task 2.3:
    
    1. Test /v1/models endpoint:
       curl http://localhost:8000/v1/models \\
         -H "Authorization: Bearer YOUR_API_KEY"
    
    2. Test /v1/cursor/models endpoint:
       curl http://localhost:8000/v1/cursor/models \\
         -H "Authorization: Bearer YOUR_API_KEY"
    
    3. Verify both return identical responses:
       {
         "object": "list",
         "data": [{
           "id": "lightreach-auto",
           "object": "model",
           "created": <timestamp>,
           "owned_by": "lightreach"
         }]
       }
    
    4. Test /v1/chat/completions endpoint:
       curl -X POST http://localhost:8000/v1/chat/completions \\
         -H "Authorization: Bearer YOUR_API_KEY" \\
         -H "Content-Type: application/json" \\
         -d '{"messages": [{"role": "user", "content": "Hello"}], "model": "gpt-3.5-turbo"}'
    
    5. Test /v1/cursor/chat/completions endpoint:
       curl -X POST http://localhost:8000/v1/cursor/chat/completions \\
         -H "Authorization: Bearer YOUR_API_KEY" \\
         -H "Content-Type: application/json" \\
         -d '{"messages": [{"role": "user", "content": "Hello"}], "model": "gpt-3.5-turbo"}'
    
    6. Verify both chat endpoints:
       - Return valid responses
       - Have identical response structure
       - Both work with streaming and non-streaming
       - Error handling is identical
    
    Expected Results:
    - All endpoints return successful responses
    - No behavioral differences between /v1 and /v1/cursor variants
    - Code is cleaner with no duplication
    - Easier to maintain (single source of truth)
