Problem

Generated registry drift was only detectable if contributors remembered to run the generator manually.

Scope

• add npm run registry:check to .husky/pre-push
• add npm run registry:check to .github/workflows/typecheck.yml

Out of scope

• separate registry-specific workflow
• broader CI restructuring

Expected files

• .husky/pre-push
• .github/workflows/typecheck.yml
• registry check script if needed

Invariants

• run freshness enforcement after API typecheck
• keep existing workflow order otherwise unchanged
• no runtime behavior changes

Validation

• npm run registry:check
• pre-push passes on the branch
