docs: add optional Parallel Search MCP setup

[georgeatparallel]

Why

This adds an optional setup for live web search and page reading to the agent-server example. Users can connect Parallel Search MCP without a Parallel account or API key, using the remote MCP client they already have.

Anonymous search uses Fast mode. Artificial Analysis currently gives it 80 F1 on DeepSearchQA and 18.4 seconds per benchmark task. DeepSearchQA tests whether an agent can research across multiple searches and put together a complete answer; time per task helps show how long users wait for that research. These are benchmark results, not timings for a Vision Agents voice call.

Changes

Adds one README section with the server configuration, where to pass it to Agent, and how to disable it. It explains rate limits and what goes to Parallel. Requests use User-Agent: Vision-Agents so Parallel can measure aggregate project usage.

Verified the documented configuration through Vision Agents' unchanged MCP client, manager, and function registry in isolation: anonymous tool discovery, Search and Fetch results, and the User-Agent on both tool requests. Full voice/video sessions weren't exercised. Documentation diff checks pass.

I work at Parallel, which operates this service.
