Subject: [PATCH] ci(release): make release creation idempotent

Previously the workflow failed with "Release.tag_name already exists"
when a release was authored manually (which auto-creates the tag and
triggers this workflow). Skip creation if the release already exists.

Also drop the now-unused checkout steps and use the GitHub API for tag
deletion in the cleanup job, which removes the need for a working tree.
