## Changes

### PR [#2092](https://github.com/danielmiessler/Fabric/pull/2092) by [Resistor52](https://github.com/Resistor52): feat(openai): add GrokAI search grounding via xAI Responses API

- Added support for GrokAI search grounding via xAI's Responses API, fixing HTTP 422 errors caused by a hardcoded OpenAI `web_search_preview` tool name in `buildResponseParams`.
- Introduced two new fields to `openai_compatible.ProviderConfig`: `WebSearchToolName` (to override the default web search tool name) and `EnableXSearch` (to append xAI's `x_search` tool when search is enabled).
- Both new fields default to empty/false, preserving full backwards compatibility for all existing providers.
- GrokAI is pre-configured with `WebSearchToolName` set to `"web_search"` and `EnableXSearch` set to `true`, enabling grounded search results with real source URLs via `fabric -V GrokAI --search`.
- Added tests in `openai_test.go` covering the new override paths and confirming default provider behavior remains unchanged.
