Feature: #109862 - stdWrap for TypoScript config.headerComment 

Description 

The TypoScript property config.headerComment now supports stdWrap . The value is evaluated in the context of the current page record before it is added as comment to the generated HTML source.

Only the comment endings --> and --!> are escaped in the evaluated value; other characters remain unchanged. This prevents dynamic values from breaking out of the HTML comment and injecting markup.

Example:

config.headerComment = (c) 2011-{date:Y} Example Inc.
config.headerComment.insertData = 1

Output:

<!--
    (c) 2011-2026 Example Inc.
-->

Impact 

Integrators can build the header comment dynamically, for example with insertData , data , wrap or if . Existing static values are rendered unchanged, except that the comment endings --> and --!> are now escaped.

As the comment is part of the cacheable page content, dynamic values are evaluated once per page cache entry.
