fix(release): add Node 22, fix CalVer version propagation

- Add actions/setup-node@v4 (Node 22) before setup-bun so semantic-release
  v25 gets a compatible runtime (requires ^22.14.0 || >=24.10.0)
- Return { nextRelease } from calver prepare so semantic-release's
  getNextInput() merge propagates the CalVer version to downstream plugins
