Fix test: use precise regex matching for command names

The test was doing naive substring matching which incorrectly found 'comment'
in command descriptions like 'Clone a PR or Issue description and comments...'

Now uses regex to extract exact command names from the Commands: section,
preventing false positives from substring matches in help text.

Also added docstring to clone_cmd wrapper for better documentation.
