Changes:

• Introduce .changeset/config.json and an initial changeset to manage versioning for @module-federation/vite.
• Enhance the Release workflow to handle latest vs next flows and add a new Release Pull Request workflow that uses module-federation/actions with Changesets.

This workflow uses actions/checkout@master, which is unpinned and goes against the convention elsewhere in this repo of pinning GitHub Actions to a major version (for example, .github/workflows/release.yml and unit-test.yml both use actions/checkout@v5). To reduce the risk of unexpected breaking changes and keep workflows consistent, consider switching this to a pinned major version such as actions/checkout@v5.
