chore: point MSD at git.golem15.com/golem15/msd-core

The fork lives on the golem15 Gitea forge, not GitHub. Package identity now
parses either host and derives in-place raw URLs for Gitea; the identity-drift
lint accepts the new host; README drops GitHub-only badges and the npm
quickstart in favour of the checkout installer.
