Add a concrete "Set up GitHub authentication" subsection to the Module 8
lab, before Part A. It walks the PAT/HTTPS path step by step on GitHub as
the worked example (fine-grained token, Contents: Read and write scope,
copy-once, paste-at-password-prompt), links GitHub's official SSH docs as
the optional alternative, and gives a pros/cons table so the learner can
choose deliberately. Extend the Verify-before-publish checklist with the
GitHub-specific menu path and scope labels, since those drift.
Closes#106
