Fix: statusline RuvNet Brain version now matches ak status

The 🧿 RuvNet Brain segment in the activation footer was showing the plugin semver (e.g. V0.5.0-dev) while ak status shows the GitHub release tag (e.g. 3.3.1) — two different version namespaces for the same install, which was confusing. The footer now reads the same release tag ak status uses (from kit.json), falling back to the plugin semver only when ak has no recorded release. Renders 🧿 RuvNet Brain V3.3.1 — consistent with status.
