chore(release): bump package.json to v0.21.21

[l5io]

Bumps package.json and package-lock.json to v0.21.21 to match the version just published to npm.

This PR is auto-generated by the Publish Node.js Package workflow after a successful npm publish --provenance so that the target branch tracks the published npm version rather than drifting behind it indefinitely. Historically this drift has confused contributors branching off master (e.g., master was at 0.16.5 while npm had published v0.18.8).

The commit message includes [skip ci] so merging this PR does not re-trigger workflows against the bump commit — the content was already CI-gated by the PR that merged into the tag.
