Upgrade ADR Kit project artifacts (the upgrade mode of setup)
Invoke explicitly with $adr-kit:upgrade when needed.
Resolve <plugin-root> from this installed skill. Use only bundled,
local ADR Kit tools and follow this canonical workflow:
- Preview ADR migration without applying it.
- Refresh only ADR Kit-owned guide, instruction blocks, and pre-commit wrapper; preserve user-owned guidance.
- Finish with strict lint and report all migration notices.
Do not contact another model or mutate user-owned instructions.
