refactor(mcp): judge stale overlays from the same config the digest was resolved from

The stale-overlay loop re-derived each name's config by hand
(`servers` first, else the profile config) right next to `resolved_ids`,
which is keyed off `judged`. Two copies of one precedence rule means an
edit to either lets the static config and the resolved digest compared
in `_same_server_route` come from different sources. Read both from
`judged`.
