Point links at the new git host

GitHub went dark with the account suspension on 2026-09-20 and GitLab was
retired on 2026-09-22, so links to either no longer resolve. Repository,
file, release and download links now point at git.coffeylabs.org, images
at registry.coffeylabs.org, and old GitHub issue and pull request links at
coffey-labs/ihasmail-github-archive, whose numbers match GitHub's.
