Summary

Adapt the aggregate HMR subscription added on canary to the napi v3 callback APIs used by the parent migration. Regenerate the native TypeScript declarations and dependency lockfiles separately so the handwritten compatibility change remains reviewable.

Verification

  • pnpm swc-build-native
  • pnpm --filter=next types
  • cargo fmt -- --check
