* fix(site-replication): keep an operator's bucket-level target to a peer instead of taking it over
Site replication wired each bucket by looking for an existing replication
target "to the same peer" and rewriting the first match in place as its own
same-name target. An operator's bucket-level target that happened to point
at that site (different target bucket, operator credentials) was the first
match whenever it pre-dated the join, and the reconciler repeats the pass
every 600s, so the takeover also depended on target order afterwards. The
operator's rule then named an ARN no target backed and their bucket
replication stopped silently, while the inherited bucket-level reset id
made every site resync report the bucket as owned by another resync
(rustfs/backlog#2479, rustfs/backlog#2489).
Follow MinIO's `getRemoteARN` / `getRemoteARNForPeer` shape instead:
- Wiring updates a target in place only under the same ARN, or when it is
recognisably the site's own under an older ARN shape (same peer,
same-name target bucket, site replication service account). Anything
else gets the site target added next to it.
- The site resync manifest takes the target the derived
`site-repl-<deployment id>` rule names (same-name shape as fallback), so
an operator target to the peer neither aborts the bucket as "multiple
remote targets matched peer" nor gets resynced into.
- Peer removal prunes only targets a pruned derived rule names or the
same-name target bucket; operator targets stamped with the peer's
deployment id survive together with their rules.
Unit tests cover the three predicates. e2e
`test_site_replication_keeps_operator_bucket_target_to_peer` runs a
bucket-level replication plus `replication-reset` to the future peer, joins
the sites, and requires the operator target untouched, both paths
delivering, the site resync completing against the site target, and the
operator target and rule surviving `replicate remove --all`; without the
fix it fails at the join with the operator target gone. The repl-nightly
selection digest is refreshed for the new case.
* test(site-replication): drop a redundant clone flagged by clippy
The reconcile unit test cloned the remote peer into the state map although
the binding is not used afterwards; workspace clippy (-D warnings) rejects
that as redundant_clone.
