web_fetch — fetch a URL as plain text

web_fetch issues a single GET request with redirects followed and a 30-second timeout. If the response is HTML, <script> / <style> blocks are removed, tags are stripped, and whitespace is collapsed. Output is truncated to 50 KB so a large page doesn’t blow the context window.
