chore(plugins): patch-bump kyberforge and lint for shipped changes

kyberforge 1.2.7 -> 1.2.8: both vale-wrap.sh copies, skill-audit's validate.sh
and its SKILL.md changed after the last bump. lint 1.1.4 -> 1.1.5: the Vale
research troubleshooting doc changed after its last bump.

Without the bump, installed copies keep serving the cached version. This is the
fourth time in this PR the bump was missed after shipped content changed —
check-manifests.sh validates parity between the two manifests but not that a
content change was accompanied by a bump, which is the gap that keeps letting
it through.
