Merge branch 'fix/gitattributes-stray-cr'

The previous commit wrote a literal carriage-return byte into a comment, where
the text was meant to show the two characters backslash-r. Git's content sniffing
treats a lone CR as a sign of binary data, so .gitattributes itself was classed
-text (git ls-files --eol reported i/-text): the one file in the template that
the new LF policy could not normalise, and one every repo created from it would
have inherited.

The rules themselves were never affected - the byte sat inside a comment.

The comment now says "a trailing CR byte" in words. .gitattributes reports
i/lf w/lf, and `git add --renormalize .` stages nothing else.
