Add Cursor IDE support via /v1/models endpoint

[konard]

Summary

This PR implements support for Cursor IDE and other OpenAI-compatible clients by adding the /v1/models endpoint to the api-gateway repository.

What Changed

Implementation (in api-gateway repository)

The actual code changes were made in the api-gateway repository:

• ✅ Added /v1/models endpoint for model discovery
• ✅ Added /v1/models/:model endpoint for individual model info
• ✅ Created comprehensive Cursor setup documentation
• ✅ Updated architecture documentation

Implementation PR: deep-assistant/api-gateway#3

Documentation (in this repository)

This PR contains:

• ISSUE-8-SOLUTION.md: Complete solution documentation explaining:
  • How the implementation works
  • How to configure Cursor IDE
  • Available models (40+ from multiple providers)
  • Technical details and API formats
  • Testing and compatibility information

How It Works

Users can now configure Cursor IDE to use the Deep Assistant API Gateway:

1. Enable OpenAI API Key in Cursor settings
2. Enter admin token from the gateway
3. Override Base URL to: https://api.deep-foundation.tech/v1
4. Verify and Save

Cursor will automatically discover all available models via the new /v1/models endpoint.

Available Models

Access to 40+ models including:

• OpenAI: GPT-4o, GPT-4o-mini, o1-preview, o1-mini, o3-mini, GPT-3.5-turbo
• Anthropic: Claude Sonnet 4, Claude 3.7 Sonnet, Claude 3.5 Sonnet, Haiku, Opus
• DeepSeek: DeepSeek Chat, DeepSeek Reasoner
• Meta: Llama 3.1 (8B, 70B, 405B)
• Microsoft: WizardLM-2 variants
• Other: Custom GPT-4.1 models, uncensored models

Technical Details

New Endpoints

GET /v1/models

{
  "object": "list",
  "data": [
    {
      "id": "gpt-4o",
      "object": "model",
      "created": 1234567890,
      "owned_by": "openai"
    }
  ]
}

GET /v1/models/:model
