fix instance type mismatch in /instance/previews endpoint

Derive instance_meta from the actual instance type returned by
place_instance() instead of using the requested instance_meta from
the loop variable. place_instance() overrides single-node placements
to MlxRing, but the preview response was still reporting the original
requested type (e.g., MlxJaccl), causing a mismatch.

Closes #1426

-## Model Cards
-
-EXO uses TOML-based model cards to define model metadata and capabilities. Model cards are stored in:
-- `resources/inference_model_cards/` for text generation models
-- `resources/image_model_cards/` for image generation models
-- `~/.exo/custom_model_cards/` for user-added custom models
-
-### Adding a Model Card
-
-To add a new model, create a TOML file with the following structure:
-
-```toml
-model_id = "mlx-community/Llama-3.2-1B-Instruct-4bit"
-n_layers = 16
-hidden_size = 2048
-supports_tensor = true
-tasks = ["TextGeneration"]
-family = "llama"
-quantization = "4bit"
-base_model = "Llama 3.2 1B"
-capabilities = ["text"]
-
-[storage_size]
-in_bytes = 729808896
-```
-
-### Required Fields
-
-- `model_id`: Hugging Face model identifier
-- `n_layers`: Number of transformer layers
-- `hidden_size`: Hidden dimension size
-- `supports_tensor`: Whether the model supports tensor parallelism
-- `tasks`: List of supported tasks (`TextGeneration`, `TextToImage`, `ImageToImage`)
-- `family`: Model family (e.g., "llama", "deepseek", "qwen")
-- `quantization`: Quantization level (e.g., "4bit", "8bit", "bf16")
-- `base_model`: Human-readable base model name
-- `capabilities`: List of capabilities (e.g., `["text"]`, `["text", "thinking"]`)
-
-### Optional Fields
-
-- `components`: For multi-component models (like image models with separate text encoders and transformers)
-- `uses_cfg`: Whether the model uses classifier-free guidance (for image models)
-- `trust_remote_code`: Whether to allow remote code execution (defaults to `false` for security)
-
-### Capabilities
-
-The `capabilities` field defines what the model can do:
-- `text`: Standard text generation
-- `thinking`: Model supports chain-of-thought reasoning
-- `thinking_toggle`: Thinking can be enabled/disabled via `enable_thinking` parameter
-- `image_edit`: Model supports image-to-image editing (FLUX.1-Kontext)
-
-### Security Note
-
-By default, `trust_remote_code` is set to `false` for security. Only enable it if the model explicitly requires remote code execution from the Hugging Face hub.
-
-## API Adapters
-
-EXO supports multiple API formats through an adapter pattern. Adapters convert API-specific request formats to the internal `TextGenerationTaskParams` format and convert internal token chunks back to API-specific responses.
-
-### Adapter Architecture
-
-All adapters live in `src/exo/master/adapters/` and follow the same pattern:
-
-1. Convert API-specific requests to `TextGenerationTaskParams`
-2. Handle both streaming and non-streaming response generation
-3. Convert internal `TokenChunk` objects to API-specific formats
-4. Manage error handling and edge cases
-
-### Existing Adapters
-
-- `chat_completions.py`: OpenAI Chat Completions API
-- `claude.py`: Anthropic Claude Messages API
-- `responses.py`: OpenAI Responses API
-- `ollama.py`: Ollama API (for OpenWebUI compatibility)
-
-### Adding a New API Adapter
-
-To add support for a new API format:
-
-1. Create a new adapter file in `src/exo/master/adapters/`
-2. Implement a request conversion function:
-   ```python
-   def your_api_request_to_text_generation(
-       request: YourAPIRequest,
-   ) -> TextGenerationTaskParams:
-       # Convert API request to internal format
-       pass
-   ```
-3. Implement streaming response generation:
-   ```python
-   async def generate_your_api_stream(
-       command_id: CommandId,
-       chunk_stream: AsyncGenerator[TokenChunk | ErrorChunk | ToolCallChunk, None],
-   ) -> AsyncGenerator[str, None]:
-       # Convert internal chunks to API-specific streaming format
-       pass
-   ```
-4. Implement non-streaming response collection:
-   ```python
-   async def collect_your_api_response(
-       command_id: CommandId,
-       chunk_stream: AsyncGenerator[TokenChunk | ErrorChunk | ToolCallChunk, None],
-   ) -> AsyncGenerator[str]:
-       # Collect all chunks and return single response
-       pass
-   ```
-5. Register the adapter endpoints in `src/exo/master/api.py`
-
-The adapter pattern keeps API-specific logic isolated from core inference systems. Internal systems (worker, runner, event sourcing) only see `TextGenerationTaskParams` and `TokenChunk` objects - no API-specific types cross the adapter boundary.
-
-For detailed API documentation, see [docs/api.md](docs/api.md).
-
 ## Testing
 
 EXO relies heavily on manual testing at this point in the project, but this is evolving. Before submitting a change, test both before and after to demonstrate how your change improves behavior. Do the best you can with the hardware you have available - if you need help testing, ask and we'll do our best to assist. Add automated tests where possible - we're actively working to substantially improve our automated testing story.

-
-**Security Note:**
-
-Custom models requiring `trust_remote_code` in their configuration must be explicitly enabled (default is false) for security. Only enable this if you trust the model's remote code execution. Models are fetched from HuggingFace and stored locally as custom model cards.
-
 **Other useful API endpoints*:**
 
 - List all models: `curl http://localhost:52415/models`
-- List downloaded models only: `curl http://localhost:52415/models?status=downloaded`
-- Search HuggingFace: `curl "http://localhost:52415/models/search?query=llama&limit=10"`
 - Inspect instance IDs and deployment state: `curl http://localhost:52415/state`

-## 8. Notes
+## 7. Notes
 
-### API Compatibility
-
-EXO provides multiple API-compatible interfaces:
-
-* **OpenAI Chat Completions API** - Compatible with OpenAI clients and tools
-* **Claude Messages API** - Compatible with Anthropic's Claude API format
-* **OpenAI Responses API** - Compatible with OpenAI's Responses API format
-* **Ollama API** - Compatible with Ollama and tools like OpenWebUI
-
-Existing OpenAI, Claude, or Ollama clients can be pointed to EXO by changing the base URL.
-
-### Custom Models
-
-You can add custom models from HuggingFace using the `/models/add` endpoint. Custom models are identified by the `is_custom` field in model list responses.
-
-**Security:** Models requiring `trust_remote_code` must be explicitly enabled (default is false) for security. Only enable this if you trust the model's remote code.
-
-### Usage Statistics
-
-Chat completion responses include usage statistics with:
-
-* `prompt_tokens` - Number of tokens in the prompt
-* `completion_tokens` - Number of tokens generated
-* `total_tokens` - Sum of prompt and completion tokens
-
-### Request Cancellation
-
-You can cancel active requests by:
-
-1. Closing the HTTP connection (for streaming requests)
-2. Calling `/v1/cancel/{command_id}` (for any request)
-
-The server detects cancellation and stops processing immediately.
-
-### Instance Placement
-
-The instance placement endpoints allow you to plan and preview cluster allocations before creating instances. This helps optimize resource usage across nodes.
-
-### Observability
-
-The `/events` and `/state` endpoints are primarily intended for operational visibility and debugging.
+* The `/v1/chat/completions` endpoint is compatible with the OpenAI Chat API format, so existing OpenAI clients can be pointed to EXO by changing the base URL.
+* The `/v1/images/generations` and `/v1/images/edits` endpoints are compatible with the OpenAI Images API format.
+* The instance placement endpoints allow you to plan and preview cluster allocations before actually creating instances.
+* The `/events` and `/state` endpoints are primarily intended for operational visibility and debugging.

     Implements a distributed algorithm for master election in unstable networking conditions
 
-## API Layer
-
-The API system uses multiple adapters to support multiple API formats, converting them to a single request / response type.
-
-### Adapter Pattern
-
-Adapters convert between external API formats and EXO's internal types:
-
-```
-Chat Completions → [adapter] → TextGenerationTaskParams → Application
-Claude Messages  → [adapter] → TextGenerationTaskParams → Application
-Responses API    → [adapter] → TextGenerationTaskParams → Application
-Ollama API       → [adapter] → TextGenerationTaskParams → Application
-```
-
-Each adapter implements two key functions:
-1. **Request conversion**: Converts API-specific requests to `TextGenerationTaskParams`
-2. **Response generation**: Converts internal `TokenChunk` streams back to API-specific formats (streaming and non-streaming)
-
