Poem

A rabbit hops through help output,
Finds ML-KEM without a doubt.
One grep checks the magic sign,
Pipeline status draws the line.
“Supported!” cheers this bunny fine. 🐇

Code Review

This pull request adds support for the 'mechanism-mlkem' mechanism in the Java CLI test script (xtest/sdk/java/cli.sh) by executing the command-line tool and checking for 'mlkem:768' in the help output. There are no review comments, and I have no feedback to provide.
