Merge pull request 'Point links at git.coffeylabs.org after the move from GitHub' (#5) from fix/links-after-move into main

GitHub took the organization's repos and GHCR offline on 2026-09-20. Repo,
release, raw-file and clone links now go to Gitea at git.coffeylabs.org,
container images to registry.coffeylabs.org, and GitLab-style /-/blob paths
to Gitea's /src/branch form. Go module paths are identifiers and stay as
they are; links to GitHub issues and pull requests are left as history.

+# The shape is the same as before -- tag-driven, amd64 and arm64,
+# reproducible. GitLab needed a generic package registry plus release-cli
+# links; Gitea attaches the tarballs to the Release itself, as GitHub did, so
+# the build and the release are one job and nothing is handed between jobs.
