Rewrite README to match locked TS conventions; minor tool/doc tweaks

Reflects the resolved wayfinder map (issue #1): no build process ever,
separate MCP server process + registration per backend, no lint/format
tooling. Also includes small wording tweaks to the qwen_delegate tool
description and timeout comment made outside this session.
