Honor configured rerank top_k in web_search defaults

invoke() always uses args.top_k (defaulting to 5) when reranking, so WebSearchToolConfig.rerank.top_k from tools_config is effectively ignored unless the model explicitly supplies top_k in each tool call. This causes configured rerank depth to be silently bypassed, which can skew result quality and performance in production setups relying on declarative tool config.
