Description

When publishing a prerelease version to npm, npm publish requires a --tag flag — otherwise it errors with:

You must specify a tag using --tag when publishing a prerelease version.

This PR checks github.event.release.prerelease in all Node.js CD workflows and publishes with --tag next for prereleases, or as latest (default) for stable releases.

Workflows updated:

• openclaw-cd.yml
• cli-node-cd.yml
• ts-sdk-cd.yml
• vercel-ai-cd.yml
