The push-triggered mirror-gitee-release job consumes the same run's
finalized-release-dist artifact, so it cannot mirror a tag that was
already published — including one delivered by a recovery dispatch such
as v1.0.53-beta.3. Add a workflow_dispatch repair-gitee job (input
mirror_gitee_version) that re-derives the asset set from the immutable
GitHub Release, verifies it byte-for-byte via checksums, and runs
sync-to-gitee.sh. Guarded to the official repo + default branch and
gated by the existing Gitee secrets.
