Subject: [PATCH] fix: retry major-tag move to survive transient 422 after
 release merge
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The release commit can briefly return "Reference does not exist" (HTTP 422)
immediately after the release PR merges — the object is not yet ref-able. The
v1 tag had to be created by hand for v1.1.0. Wrap the create/update in a 5x
retry with backoff so the moving major tag lands automatically.
