Propagate the 9.5.1 patch version into the Claude and Codex
plugin manifests plus the generated Claude marketplace metadata.
This keeps release:preflight from leaving tracked changes after the
release sync step.
Refs #445
Record the versioned plugin metadata and onboarding docs refreshed by the release preflight so the release workflow can continue from a clean main branch.
Expand the conservative risk sync with explicit critical, offensive, and none patterns.\n\nAuto-apply high-confidence legacy label fixes, add the authorized-use notice when promoting offensive skills, and regenerate canonical and plugin artifacts so the unknown backlog keeps shrinking without loosening contributor input rules.
Add a maintainers script to safely promote high-confidence legacy risk labels from unknown to concrete values, cover it with tests, and regenerate the canonical skill artifacts and plugin copies. This reduces the legacy unknown backlog without forcing noisy classifications that still need manual review.
Capture the plugin manifest version bumps that release:prepare generated for 9.0.0 and update the release staging step so Claude and Codex plugin manifests are included automatically in future release commits.
