git.cafe's main was missing the Emc² rename (3fc4d30, merged on GitHub as
5df470a) and the mail-links merge (PR #4). Both are now in the history, and
the emc2 rename is carried into this host rather than living on GitHub alone.

Conflicts in package.json, CONTRIBUTING.md and docs/KB.md were wording and
glob-order only; the rename side was kept and the test globs unified.
