ci: add Vercel deployment workflow (renamed)

Add automatic deployment workflow to Vercel.

This workflow:
- Runs on every push to main and on pull requests
- Creates preview deployments for pull requests
- Deploys to production when changes are merged to main
- Uses Vercel for fast and efficient deployments

Requires VERCEL_TOKEN, VERCEL_ORG_ID, and VERCEL_PROJECT_ID secrets to be configured.
