* test(heal): add concurrency invariants for heal vs delete/overwrite races (HS-12) Audit conclusion for backlog#1874: RustFS does not need a persistent object-level healing marker (MinIO x-minio-healing) because every path that can touch the same (bucket, object) commit surface serializes on the same namespace write lock, and the heal lock guard spans the whole rename commit including the HEAL_RENAME_INCOMPLETE partial path. Lock the conclusion in with two race regression tests: - heal_racing_version_delete_never_resurrects_the_deleted_version: shard damage is injected on the doomed version so a Deep heal has real reconstruction work while a versioned DELETE runs concurrently; the deleted version must stay deleted and the survivor intact. - heal_racing_unversioned_overwrites_preserves_the_last_commit: unversioned overwrites (activating the post-commit tail that deletes the replaced data dir without the ns lock) race a Deep heal in a loop; the final current version must be exactly the last commit. Also adds docs/operations/heal-concurrency-safety-notes-zh.md with the full intersection matrix (17 intersections), lock-coverage argument, and the residual-window classification (commit tail races are fail-into-retry safe; bare prefix delete has zero production callers; admin no_lock is an explicit operator opt-in).
