docs: add optional Parallel web research guide for Claude Code

[georgeatparallel]

Summary

Give Claude Code sessions using Evolver free web search and page fetching with Parallel Search MCP. The guide uses Fast mode search without an account or API key, with an opt-in setup local to one project.

I work at Parallel.

What changed

• Add a setup, error-research prompt and removal guide alongside Evolver's existing Claude Code hooks.
• Link it from the quick start and explain which information goes to the external service.

How to test

1. Follow the add/get commands in examples/parallel-research.md; the server should report HTTP transport and a connected status in Claude Code.
2. Try the research prompt with a redacted error, then run the documented remove command.
3. Run node index.js; expect a GEP prompt. The CLI sanity check passed with disposable runtime state. Setup and removal passed with Claude Code 2.1.302; anonymous search and page fetching were checked directly through MCP.

Risk

Low: documentation only. Web research is explicitly enabled in the host session; Evolver runtime defaults and skill permissions stay unchanged.

Note

Low Risk
Documentation-only; no runtime, config, or Evolver skill permission changes.

Overview
Adds an optional Parallel Search MCP walkthrough so Claude Code users running Evolver can research unfamiliar errors via anonymous web search and page fetch, without changing Evolver runtime or hooks.

The new examples/parallel-research.md covers local claude mcp add/remove for evolver-parallel-search, verification via /mcp, a sample research prompt (e.g. Windows spawn EINVAL), and privacy notes about queries going to Parallel. Hello World’s “Next steps” now links to that guide.
