- M2 lab now `git init -b main` (with older-git fallback note) so every later
`main` reference resolves; reconciled M3/M6/M7/M8 wording and M10's standalone
review-lab repo (`git init -qb main`).
- M9: replace "issues are on by default on every forge" with a provider-neutral
version naming the exceptions (Bitbucket/Azure DevOps/SourceHut).
- M14: qualify "hosted runners need zero setup" — true for SaaS forges; the
self-hosted track needs a runner attached (Module 19). Both paths stay valid.
