# Vector-sync HTTP embedding provider

This patch adds a new provider type:

- `http-vector-sync`

## Request
Endpoint:
- `POST {baseUrl}/vector-sync`

Request body:
```json
{
  "model": "intfloat/multilingual-e5-large",
  "text": "This is a sample text to vectorize"
}
```

## Response
```json
{
  "runtime_ms": 472.49,
  "vector": [0.1, 0.2, 0.3],
  "incomplete": false,
  "combined_vector": null,
  "token_count": 9,
  "model": "intfloat/multilingual-e5-large",
  "max_seq_length": 512
}
```

## Notes
- supports a single text per request
- works for both document and query embeddings
- validates returned vector dimension against the configured embedding model
- keeps the existing `/embed` provider in place as `http-json`

## Example config
See `application-new-example-vector-sync-provider.yml`.
