Copilot 98c3bbbaf0 fix(ollama): num_gpu parameter not working in async OllamaEmbeddings method (#32074)
The `num_gpu` parameter in `OllamaEmbeddings` was not being passed to
the Ollama client in the async embedding method, causing GPU
acceleration settings to be ignored when using async operations.

## Problem

The issue was in the `aembed_documents` method where the `options`
parameter (containing `num_gpu` and other configuration) was missing:

```python
# Sync method (working correctly)
return self._client.embed(
    self.model, texts, options=self._default_params, keep_alive=self.keep_alive
)["embeddings"]

# Async method (missing options parameter)
return (
    await self._async_client.embed(
        self.model, texts, keep_alive=self.keep_alive  #  No options!
    )
)["embeddings"]
```

This meant that when users specified `num_gpu=4` (or any other GPU
configuration), it would work with sync calls but be ignored with async
calls.

## Solution

Added the missing `options=self._default_params` parameter to the async
embed call to match the sync version:

```python
# Fixed async method
return (
    await self._async_client.embed(
        self.model,
        texts,
        options=self._default_params,  #  Now includes num_gpu!
        keep_alive=self.keep_alive,
    )
)["embeddings"]
```

## Validation

-  Added unit test to verify options are correctly passed in both sync
and async methods
-  All existing tests continue to pass
-  Manual testing confirms `num_gpu` parameter now works correctly
-  Code passes linting and formatting checks

The fix ensures that GPU configuration works consistently across both
synchronous and asynchronous embedding operations.

Fixes #32059.
