Active-active conflict resolution for concurrent tag/retention/legal-hold
edits needs the source's per-category modification times on both sides of
the wire; the three AdvancedPutOptions timestamp fields were dead and the
headers were neither sent nor parsed.
- Emit x-{rustfs,minio}-source-replication-{tagging,retention,legalhold}-
timestamp from PutObjectOptions::header(); names and RFC3339 values
interoperate with MinIO (minio-go constants.go, object-api-options.go),
pinned by a header_compat wire-name test.
- Default the three AdvancedPutOptions timestamps to UNIX_EPOCH and skip
epoch values in header(), so "never modified" is not sent as a
modification made now.
- Parse the headers only on authorized replication PUTs and multipart
completes, expose them as Option<OffsetDateTime> on ObjectOptions, and
persist them into the dual-prefix internal metadata keys so the
outbound pass (replication_target_boundary) reads the source's
timestamps instead of the mod_time fallback.
- Record the local tagging timestamp in the PutObjectTagging and
DeleteObjectTagging eval metadata, mirroring the object-lock handlers;
without it the sender only ever had the mod_time fallback to offer.
Receiver-side LWW comparison (keep newer stored category metadata over a
stale inbound copy) is left as a TODO at the parse site.
