ci(release): idempotent registry publish — survive re-tagged releases

A moved release tag re-fires the publish workflows, and the Gitea
registries reject duplicate uploads with 409 (deb pool, rpm group, and
the generic packages' versioned URLs; the channel aliases already
pre-deleted). Delete any prior copy of the exact version before
uploading (404 on first publish tolerated), so a republished tag
overwrites instead of wedging — v0.5.0's retag left stale no-port-change
artifacts published and every re-run red.
