Subject: [PATCH] fix: use CDATA sections in XML examples to prevent parser
 errors

The root cause of issue #4852 was that the XML examples in the tool
description contained unescaped markdown backticks which confused the
fast-xml-parser. Using CDATA sections properly escapes this content.

This is the actual fix - no fallback parser or workarounds needed.
