Setup, configuration and deployment docs live in website/, which is
published as the docs site, but the map sent them to /docs and did not
list website/ at all. Add it, and drop the "when those paths are used"
hedge on /specs, which exists.
CODEOWNERS has no rules until #593 settles the per-area map; say so
instead of describing reviewers it does not list.
CONTRIBUTING.md still had a single maintainer curating main, which the
Release Maintainer section replaces. Name the Product Owner's GitHub
account and say where a community proposal starts, matching the
existing issue forms.
Adapt the agreed maintainer responsibilities and risk-based review policy for the public repository. Add evidence-driven security review, CodeQL triage, release guidance and a discoverable contributing link.
