Patch Changes

• 165d531: deprecate searchParameters (xai live search) in favor of web_search/x_search agent tools

• 4d53460: feat(provider/xai): add enableImageSearch to the xAI Web Search tool

  The xAI Responses API supports enable_image_search on Web Search tools. xai.tools.webSearch() now accepts enableImageSearch and sends it through to the API as enable_image_search.
