✨ S3UTILS-230 implement CRR multi-site V2 replication format

[DarkIsDude]

Summary

• Add V2 replication format support to `ReplicationStatusUpdater`, implementing the CRR to Multiple Sites design
• V2 configs (rules with a `Filter` element) route through a new `_markObjectPendingV2` path that writes per-backend `destination`/`role` and removes legacy top-level `storageClass`/`storageType`/`destination`
• V1 configs (no `Filter` on any rule) retain existing behavior unchanged
• Arsenal static methods (`resolveBackends`, `resolveSourceRole`, `resolveDestinationRole`) are reused instead of maintaining parallel implementations; arsenal dependency pinned to `improvement/ARSN-571/crr-multi`

Changes

`CRR/ReplicationStatusUpdater.js`

• `_isV1Format()` — V2 detection aligned with arsenal: a rule is V2 if it carries a `Filter` element
• `_getMatchingRules()` — prefix-matches object key against enabled rules, deduplicates by site (highest priority wins); feeds the adapter for `resolveBackends`
• `_computeTopLevelStatus()` — aggregates backend statuses: FAILED > PROCESSING > COMPLETED
• `_removeV1Fields()` — strips legacy top-level `storageClass`/`storageType`/`destination` when migrating to V2
• `_markObjectPendingV2()` — V2 metadata writer: adapts AWS SDK rule shape to arsenal's `ReplicationConfigurationMetadata`, calls `ReplicationConfiguration.resolveBackends` for prefix matching / priority dedup / per-backend destination+role stamping, then calls `resolveSourceRole` for the top-level role

`package.json` — arsenal pinned to `improvement/ARSN-571/crr-multi` for the new static methods

`tests/utils/crr.js` — V2 bucket replication config fixture

`tests/unit/CRR/ReplicationStatusUpdater.js` — 7 new V2 test cases (single match, dual-rule prefix overlap, no-match skip, SITE_NAME filter, all-up-to-date skip, PROCESSING aggregate status, forceUsingConfiguration)

Test plan

• All 456 unit tests pass (`yarn test:unit`)
• Lint clean (`yarn lint`)
• V2 metadata written with per-backend `destination`/`role` and no legacy top-level fields
• V1 configs produce identical output to before this change

Can be simplified a lot by using arsenal logic

One final batch of reviews and we should be good to go 💪

Used once, could be inlined to simplify code reading.

[DarkIsDude]

It was intended here. As the function is waterflow, with old style and very long, I specifically tried to split it. If it's a hard no for you, I can change 🙏

[maeldonn]

Since this is only used once, it could be inlined. While extracting logic to an external function usually improves readability, creating small functions for single-use cases can actually make the code harder to follow
