Subject: [PATCH] Prevent redundant releases in GitHub Actions

Added conditional logic to skip unnecessary release steps if the version tag already exists or if the version hasn't changed. This optimization avoids redundant operations by ensuring release-related jobs are executed only when needed, thus enhancing workflow efficiency.
