fix(release): preserve prerelease state during publish

[up2dul]

Summary

• temporarily mask Changesets prerelease state while publishing with the recorded npm tag
• restore prerelease state after successful and failed publish attempts
• document the new-package dist-tag exception and add subprocess regression coverage

Recovery

This PR intentionally has no Changeset. Merging it triggers a new release workflow run that publishes the already-versioned profanity-kit@0.1.0-next.2. Do not rerun the failed workflow because it is pinned to the broken commit.

Validation

• pnpm check
• pnpm package:artifact
• pnpm docs:check
• pnpm docs:build
