PR Summary

Medium Risk
Touches the release/publish path for public packages; a misconfiguration could affect npm publishes, though the change is limited to one script line.

Overview
Updates the root release script so publishing runs through pnpm publish -r --access=public instead of changeset publish, after the existing filtered package build step.

This matches pnpm’s recommended Changesets release flow and keeps public registry access explicit on the publish command.
