Enhance CI/CD workflow with commit verification

Added a step to fetch the `origin/main` branch with a depth of 1
in the `cd-release.yml` workflow. Introduced a step to verify
that the current commit exists in the `origin/main` branch by
checking if the branch contains the commit. These changes
ensure consistency and validate that the release process
operates on a valid commit from the main branch.
