Host/instance configuration (domain, port, registry, global concurrency)
lives in a .werkator.yml in the home directory of the user running the
instance — one instance per OS user, matching the platform model; repo
configuration stays in each repository's .git/werkator/. Repo-level
instance keys get ignored with a warning once a home config exists.
The open questions now name the decisions still needed: repo defaults
in the home file, cwd-vs-registry precedence, repo naming, and whether
the third .werkator.yml location should carry a distinct name.
